[jira] [Commented] (HBASE-9730) Exceptions in multi operations are
not handled correctly
[ https://issues.apache.org/jira/browse/HBASE-9730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13789922#comment-13789922 ]
Sergey Shelukhin commented on HBASE-9730:
-----------------------------------------
According to our observation IOException from batch mutate might be RegionNotServedException when region is closing. So it seems like it;s consistent with observation.
I can give +1 but my understanding of RPC code is limited
