[jira] Commented: (HBASE-2522) Disabling a table during a split
(tricky) can leave the daughter regions assigned and marked offline in
.META.
[ https://issues.apache.org/jira/browse/HBASE-2522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12904915#action_12904915 ]
stack commented on HBASE-2522:
------------------------------
This should not be possible in new master. Disable/enable of a table is a flag in zk, not state of region online/offline flag. Leaving open till we write a unit test to prove that this no longer possible under new master.

> If for any reason the master takes too much time to process a MSG_REPORT_SPLIT_INCLUDES_DAUGHTERS, and that a user successfully disables the table, then the daughter regions will still be assigned and marked as offline in .META.
> A test case I'm uploading to HBASE-2515 shows the issue.
