------------------------------

             Summary: MergeTableRegionsProcedure failed due to ArrayIndexOutOfBoundsException
                 Key: HBASE-17529
                 URL: https://issues.apache.org/jira/browse/HBASE-17529
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu


I built tar ball using master branch based on commit 616f4801b06a8427a03ceca9fb8345700ce1ad71.

Was running the following command:

hbase org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList -DinMemoryCompaction=BASIC
Loop 4 6 1000000 /tmp/hbase-biglinkedlist-verify 6 --monkey slowDeterministic

Here was related snippet:
