[jira] [Commented] (HBASE-17529) MergeTableRegionsProcedure failed
due to ArrayIndexOutOfBoundsException
[ https://issues.apache.org/jira/browse/HBASE-17529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15854411#comment-15854411 ]
Ted Yu commented on HBASE-17529:
--------------------------------
MergeTableRegionsProcedure#MoveRegionsToSameRS() code path was verified to be working (on Jan 25th).
The cause of exception seems to be related to how MultiByteBuff handles data transfer.
