[jira] [Comment Edited] (HBASE-13471) Fix a possible infinite loop in doMiniBatchMutation

    [ https://issues.apache.org/jira/browse/HBASE-13471?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14509650#comment-14509650 ]

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

Maybe this can be caused when the client's cache is slightly out of date? The usual protocol is to have the RPM at the region server fail and the client should try again. For batch mutations that appears to be broken than?! That would be unbelievably bad!
