Known Issues Fixed in CDH 5.0.2

The following topics describe known issues fixed in CDH 5.0.2. See What's New in CDH 5.0.2 for a list of the most important upstream problems fixed in this release.

Apache Hadoop

CDH 5 clients running releases 5.0.1 and earlier cannot use WebHDFS to connect to a CDH 4 cluster

For example, a hadoop fs -ls webhdfs command run from the CDH 5 client to the CDH 4 cluster produces an error such as the following:
Found 21 items
ls: Invalid value  for webhdfs parameter  "op": No  enum const class org.apache.hadoop.hdfs.web.resources.GetOpParam.Op.GETACLSTATUS

Bug: HDFS-6326

Severity: Medium

Workaround: None; note that this is fixed as of CDH 5.0.2.

Apache HBase

— Endless Compaction Loop

If an empty HFile whose max timestamp is past its TTL (time-to-live) is selected for compaction, it is compacted into another empty HFile, which is selected for compaction, creating an endless compaction loop.

Bug: HBASE-10371

Severity: Medium

Workaround: None
