Using Pig with HBase
To allow Pig scripts to use HBase, add the following statement to the top of each script. Replace the <component_version> strings with the current HBase, ZooKeeper and CDH version numbers.
register /usr/lib/zookeeper/zookeeper-<ZooKeeper_version>-cdh<CDH_version>.jar register /usr/lib/hbase/hbase-<HBase_version>-cdh<CDH_version>-security.jar
register /usr/lib/zookeeper/zookeeper-3.4.5-cdh5.0.0.jar register /usr/lib/hbase/hbase-0.95.2-cdh5.0.0-security.jar
In addition, Pig needs to be able to access the hbase-site.xml file on the Hadoop client. Pig searches for the file within the /etc/hbase/conf directory on the client, or in Pig's CLASSPATH variable.
