Issues Fixed in CDH 5.7.1
The ReplicationCleaner process can abort if its connection to ZooKeeper is inconsistent
If the connection with ZooKeeper is inconsistent, the ReplicationCleaner may abort, and the following event is logged by the HMaster:
WARN org.apache.hadoop.hbase.replication.master.ReplicationLogCleaner: Aborting ReplicationLogCleaner because Failed to get list of replicators
Unprocessed WALs accumulate.
The seekBefore() method calculates the size of the previous data block by assuming that data blocks are contiguous, and HFile v2 and higher store Bloom blocks and leaf-level INode blocks with the data. As a result, reverse scans do not work when Bloom blocks or leaf-level INode blocks are present when HFile v2 or higher is used.
Workaround: Restart the HMaster occasionally. The ReplicationCleaner restarts if necessary and process the unprocessed WALs.

Issues Fixed in CDH 5.7.0
TailDirSource throws FileNotFound Exception if ~/.flume directory is not created already
This fix ensures that any missing parent directories in the positionFile path (either default or user given input) are always created.
flume_env script should handle JVM parameters like -javaagent -agentpath -agentlib
This fix enables the flume_env script to handle JVM parameters such as -javaagent -agentpath and -agentlib.
Kafka channel timeout property is overridden by default value
When the Kafka channel timeout property is passed to the Kafka consumer internally, it does not work as expected. It is overridden by the default value or the value specified by the .timeout property, which is undocumented. Now the kafka.consumer.timeout.ms value specified in the configuration takes effect like other Kafka consumer properties.
ReplicationMonitor can infinitely loop in BlockPlacementPolicyDefault#chooseRandom()
When a large number of nodes are removed by refreshing node lists, the network topology is updated and the replication monitor thread may get stuck in the while loop of chooseRandom().
Clean up temporary files after fsimage transfer failures
When an fsimage (or checkpoint) transfer fails, a temporary file is left in each storage directory. If the namespace is large, these files can take up a large amount of space.
Lease recovery should return true if the lease can be released and the file can be closed
FSNamesystem#recoverLease should return true when a lease is recovered both explicitly and implicitly—that is, when a lease recovery is successful and the file is closed, and also when a file is closed and the lease is released without a recovery.
fsck does not list correct file path when bad replicas or blocks are in a snapshot
When blocks are corrupt in a snapshot, the fsck command lists the original directory and not the snapshot directory. This happens even when the original file is deleted. The specific commands are fsck -list-corruptfileblocks and fsck -list-corruptfileblocks -includeSnapshots.
Make DataStreamer#block thread safe and verify generationStamp in commitBlock
When the client calls updatePipeline, a block might commit with an old generationStamp, causing replicas to look corrupt.
Delayed heartbeat processing causes storm of subsequent heartbeats
The NameNode usually handles DataNode heartbeats quickly, but can be delayed for various reasons, such as a long garbage collection or lock contention. After the NameNode recovers, the DataNode sends a storm of heartbeat messages in a tight loop which, in a big cluster, can overload the NameNode and make cluster recovery difficult.
FSImage may get corrupted after deleting snapshot
When deleting a snapshot that contains the last record of a given INode, the fsimage may become corrupt because the create list of the snapshot diff in the previous snapshot and the child list of the parent INodeDirectory are not cleaned.
See also Known Issues In CDH 5.7.0.
Potential data loss after a RegionServerAbortedException
If the master attempts to assign a region while handling a RegionServer abort, the returned RegionServerAbortedException is handled as though the region had been cleanly taken offline, so the new assignment is allowed to proceed. If the region is opened in its new location before WAL replay has completed, the replayed edits are ignored, or are later played back on top of new edits that happened after the region was opened. In either case, data can be lost.
Data loss can occur if a table has more than 2,147,483,647 columns
Data loss can occur if a table has more than 2,147,483,647 (Integer.MAX_INT) columns, because some key variable types are INT rather than LONG.
Workaround: Adjust your schema to use fewer than Integer.MAX_INT columns.
Delete operations that occur during a region merge may be eclipsed by new Put operations
The master's timestamp is not used when sending hbase:meta edits on region merges, so correct ordering of new region additions and old region deletes is not assured and data loss can occur if edits are applied in the wrong order.
RPC handler / task monitoring seems to be broken after 0.98
After pluggable RPC scheduler, the way the tasks work for the handlers got changed. We no longer list idle RPC handlers in the tasks, but we register them dynamically to TaskMonitor through CallRunner. However, the IPC readers are still registered the old way (meaning that idle readers are listed as tasks, but not idle handlers).
From the javadoc of MonitoredRPCHandlerImpl, it seems that we are NOT optimizing the allocation for the MonitoredTask anymore, but instead allocate one for every RPC call breaking the pattern
Conflicts between HBase Balancer and hbase:meta reassignment
If hbase:meta is assigned to a RegionServer that becomes unavailable, and the HBase balancer has scheduled but not completed a plan to move hbase:meta to a different RegionServer, the hbase:meta becomes unassigned.
Regions can fail to transition in a write-heavy cluster with a small number of read handlers
On a write-heavy cluster configured with a small number of read handlers, all requests that are not mutations are sent to the read handlers, including ReportRegionInTransition requests. If these requests time out, the RegionServer is assumed to be unavailable, and the regions cannot transition correctly.
In a secured environment, when a RegionServer is stopped, znodes may not be cleaned up correctly
When a RegionServer process is stopped, the zkcli command is invoked to delete its znodes. In a secure cluster, the zkcli command does not authenticate to ZooKeeper and the deletion fails. This problem occurs because the REGIONSERVER_OPTS environment variable is not correctly passed when invoking the zkcli command.
Delays in RegionServer responses can cause a region to be closed indefinitely
Handling of region assignment by the master has a flaw when RegionServer responses are delayed due to network delays, system load, or other reasons. This flaw can cause the master to close a region indefinitely.
Workaround: Restart the RegionServer to force the region to be reassigned.
When a RegionServer crashes, replication peers can crash due to inode exhaustion from old WALs
The fix for HBASE-12865 ensures that loadWALsFromQueues attempts a retry when the replication source version is changed while loading the replication queue. However, the fix introduced a bug in ReplicationLogCleaner that causes an infinite loop when a RegionServer crashes. As a result, old WALs are not cleaned up. In a cluster under high load, the inode limit on the replication peer RegionServer can be exhausted, causing the RegionServer to crash.
When a RegionServer crashes, cell-level visibility tags may be lost during WAL replay
When reading cells after a RegionServer crash, the KeyValueCodec and the WallCellCodec both use NoTagsKeyValue, which does not preserve visibility tags.
Column is not deleted if you do not pass the visibility label
If a column was created or modified with a visibility label, and you attempt to delete it without passing the visibility label, the column is not deleted. It is not visible using a Scan operation, but is visible using a raw Scan, and is marked with deleteColumn.
If multiple users are configured with the role hbase.superuser, an attempt to connect to a secure ZooKeeper instance fails
The hbase.superuser configuration option is a comma-separated list of users. A bug in the code to connect to a secure ZooKeeper causes the list to be evaluated as a single value, so a list of multiple users fails because no username matches the comma-separated list.
Workaround: Only specify a single user in the hbase.superuser configuration option.
Region split request audits are performed against the hbase user instead of the requesting user
When checking whether the requesting user has permission to perform a region split, the hbase user's permissions are checked instead of those of the requesting user.Due to this bug, CREATE is sufficient for the split, rather than CREATE and ADMIN. Because CREATE permissions are also sufficient for flushes and compactions, this issue is not severe in most environments.
Incorrect timestamp checking causes unpredictable deletes with VisibilityScanDeleteChecker.
Incorrect timestamp checking when VisibilityScanDeleteChecker is used causes unpredictable results when deleting cells. In some cases, the timestamp is deleted but the cell contents are not deleted. In other cases, a request to delete an entire row or to delete a version results in only a single cell being deleted.
A BulkLoad of an HFile with tags that requires splits does not preserve the tags
When an HFile is created with cell tags and is imported into HBase using a bulk load, the tags are present as expected when the HFile is loaded into a single region. However, if the bulk load spans multiple regions, the original HFile is automatically split into a set of HFiles corresponding to each of the regions the original HFile covers. Tags, including ACLs, TTLs, and MOB pointers, are not copied to the split files.
Restoring a snapshot from a table in a user-defined namespace causes a URISyntaxException
A table in a user-defined namespace uses a colon between the namespace and the table name (for instance, example_ns:users). This colon is interpreted incorrectly when restoring from a snapshot.
The list_snapshots HBase shell command shows all snapshots, regardless of the user's permission to view them
A user with no privileges to interact with a snapshot can list the snapshot using the list_snapshots HBase shell command.
ExportSnapshot or DistCp operations may fail on the Amazon s3a:// protocol
ExportSnapshot or DistCP operations may fail on AWS when using certain JDK 8 versions, due to an incompatibility between AWS Java SDK 1.9.x and the joda-time date-parsing module.
Workaround: Use joda-time 2.8.1 or higher, which is included in AWS Java SDK 1.10.1 or higher.
If HDFS is restarted while HBase is running, WALs being replicated may not close correctly
The RegionServer receiving the replicated WALs has no mechanism to be notified to perform a recovery if HDFS is restarted on the source cluster.
Workaround: Restart the RegionServer to force the master to trigger the lease recovery during WAL splitting.
The permissions of the .top/ directory are not explicitly set during LoadIncrementalHFiles operations
Permissions are not explicitly set on the .top/ directory created during LoadIncrementalHFiles. The permissions should be set the same as the .bottom/ and .tmp/ directories.
Nonfatal errors in the FSHLog subsystem are incorrectly logged as fatal errors
If an IOException causes a log roll to be requested, it is logged as a fatal event, although it should be logged as a warning.
FuzzyRowFilter may omit some rows if multiple fuzzy keys are present
If you use the FuzzyRowFilter for Scan operations, and you have multiple fuzzy keys, some rows may be omitted from the RowTracker.
The prefix-tree module is not automatically included in MapReduce jobs
JARs for prefix-tree module are not automatically included in YarnChildren processes. This causes a ClassNotFoundException.
Workaround: Manually add the prefix-tree JARs to the classpath if needed.
Values of some metrics may appear to be negative
Some metric value are stored in integers, and cannot accommodate real-world values. This causes metric values to appear to be negative.
The HBase Shell cannot handle Scan filters which contain non-UTF8 characters
The HBase Shell incorrectly handles filter strings which contain non-UTF8 characters.
Reverse scans do not work when Bloom blocks or leaf-level inode blocks are present
Because the seekBefore() method calculates the size of the previous data block by assuming that data blocks are contiguous, and HFile v2 and higher store Bloom blocks and leaf-level inode blocks with the data, reverse scans do not work when Bloom blocks or leaf-level inode blocks are present when HFile v2 or higher is used.
Fix regression in bind and search logic for Hive external LDAP authentication
Fixes a regression in LDAP bind and search authentication from CDH 5.5.0.
Some queries using LEFT SEMI JOIN fail with IndexOutOfBoundsException
Some queries using LEFT SEMI JOIN fail with IndexOutOfBoundsException. Constant propagation optimization for these queries is now enabled.
BETWEEN predicate is not functioning correctly with predicate pushdown on Parquet tables
BETWEEN becomes exclusive in Parquet table when predicate pushdown (PPD) is enabled for Parquet tables, leading to potential incorrect results.
Performance degradation when running Hive queries against wide tables with Sentry enabled
Fixes a performance regression due to inefficient authorization checks in the Sentry Hive binding for Hive tables that are wide (more than 100 columns).
Optionally cancel queries after configurable timeout waiting on compilation lock
Adds a new configuration option, hive.server2.compile.lock.timeout, that cancels queries if they are waiting for the compile lock for more than this amount of time. This applies only to queries waiting on compilation and does not cancel queries that are being compiled. By default, the timeout is unlimited.
The Hive Sample Table, customer, Cannot be Queried
Users can now query the customer table in the Hive editor.
Apache Impala (incubating)
MapReduce Rolling Upgrades To and From CDH 5.6.0 Fail
Users can now safely use rolling upgrade from releases CDH 5.6.0 and lower to CDH 5.7.0.
Reordered updates cause leaders and replicas to become out of sync
Solr relied on checking leader/replica document synchronization by comparing the last 100 updates on the leader and replica for significant overlap, and then applying any missing updates from the leader. In certain cases, document updates could be significantly reordered, resulting in mismatches in the index, even when the last 100 documents matched. Solr now implements hashing over the versions of all the documents to check for synchronization, eliminating a class of errors in which replicas and leaders could become out of sync.
Fixed Sentry Oracle upgrade script
This fixes previous Sentry upgrade issues with Oracle (ORA-0955).
Tables with non-HDFS locations break Hive Metastore startup
Tables with non-HDFS locations cause the HDFS/Sentry plugin to enter an invalid state and fail with the exception, Could not create Initial AuthzPaths or HMSHandler !!.
URI check is now case-sensitive
Sentry no longer ignores case when validating privileges for URIs.
TRUNCATE on empty partitioned table in Hive fails
PathsUpdate.parsePath(path) will throw an NPE when parsing relative paths
Sentry now skips relative paths (that is, paths without a fully qualified scheme) rather than failing with a NPE.
The Sentry Server should be not be updated if the CREATE/DROP operations fail
Previously, even if a CREATE TABLE operation failed, the Sentry Server would still be updated with a path to the table. This has been fixed.
SimpleDBProviderBackend should retry the authorization process
This fix includes corrections to the retry logic to remove recursive calls and include a wait time between retries when authorization fails.
Support Hive RELOAD by updating the classpath for Sentry
When Hive issues the RELOAD command, Sentry now gets the updated auxiliary JAR path from the hive.reloadable.aux.jars.path property.
RealTimeGet with explicit ids can bypass document-level authorization
Users can no longer bypass security by guessing the document IDs for the RealTimeGet command.
Updated Apache Shiro dependency
External partitions referenced by more than one table can cause some unexpected behavior with Sentry HDFS sync
INSERT INTO command no longer requires URI privilege on partition location under table
The checks on the Hive INSERT INTO command have been relaxed. The INSERT INTO command adds location information to the partition description. Although this requires a check on URI privileges, in this case location information can be generated even if the partition is under the table directory.
Improvement to the SentryAuthFilter error message when authentication fails
Avoid logging all DataNucleus queries when debug logging is enabled
Logging DataNucleus queries when debugging can fill up 2 GB of log file space in less than five minutes.
getGroup and getUser should always return original HDFS values for paths that are not managed by Sentry
Paths that do not correspond to Hive metastore objects should not be affected by HDFS/Sentry sync.
Exceptions in MetastoreCacheInitializer should not prevent HMS from starting up
Instead of only throwing a runtime exception, this fix ensures failed tasks are first retried.
Set maximum message size for Thrift messages
This ensures that security scans and unformatted messages do not bring down the Sentry server by going out of bounds.
Allow SentryAuthorization setter path always fall through and update HDFS
Setting HDFS rules on Sentry-managed HDFS paths should not affect original HDFS rules
Removing and modifying ACLs on Sentry-managed paths that correspond to Hive metastore objects should not affect the original HDFS access rules.
Fix inconsistency in column-level privileges
If you have column-level privileges for a table, the SHOW columns operation should not require extra table-level privileges.
Spark SQL does not support the char type
Spark SQL does not support the char type (fixed-length strings). Like unions, tables with such fields cannot be created from or read by Spark.
Spark SQL statements that can result in table partition metadata changes may fail
Because Spark does not have access to Sentry data, it may not know that a user has permissions to execute an operation and instead fail it. SQL statements that can result in table partition metadata changes, for example, "ALTER TABLE" or "INSERT", may fail.
Certain Spark MLlib features not supported
- ML pipeline APIs
Streaming incompatibility between Spark 1.2 and 1.3
Applications built as a JAR with dependencies ("uber JAR") must be built for the specific version of Spark running on the cluster.
Workaround: Rebuild the JAR with the Spark dependencies in pom.xml pointing to the specific version of Spark running on the target cluster.
Spark SQL cannot retrieve data from a partitioned Hive table
When reading from a partitioned Hive table, Spark SQL cannot identify the column delimiter used and reads the full record as the first column entry.
Workaround: Contact Cloudera Support for information on how to deploy a patch to resolve the issue.
Tasks that fail due to YARN preemption can cause job failure
Tasks that are running on preempted executors will count as FAILED with an ExecutorLostFailure.
Oracle connector not working with lowercase columns
The Oracle connector now works with lowercase columns.
Run only one map task attempt during export
In most scenarios, running multiple map task attempts by default when performing an export is not required. The default is now one map task attempt during export operations.
Do not dump data on error in TextExportMapper by default
Support of glob paths during export
Glob paths are now supported for export.
Sqoop should support importing from table with column names containing some special characters
Sqoop supports some special characters in column names. The specific list of characters depends on those supported for a particular database.
Avro export ignores --columns option
AvroExportMapper now supports the --columns option to restrict the columns to export.
Java 8 (updates 60 and higher) has problems with joda-time and S3 requests
Versions of Java 1.8, from update 60 and higher (jdk1.8.0_60++), cause S3 to fail because joda-time cannot format time zones.
