When trying to use Apache Pig in local mode to connect to a stand-alone HBase using HBaseStorage, I kept getting errors like this:
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2999: Unexpected internal error. Not a host:port pair: ?42548@endive.local10.1.10.70, 64058,1341349176322
The unrecognized host:port pair corresponds to a happy sign-on message from the HBase log:
INFO org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper: The identifier of this process is 42548@endive.local
The problem is a version mismatch: HBase apparently changed the format of this data in 0.92. As of Pig 0.10.0, the solution is downgrade HBase to 0.90.6.
