Subject [jira] [Commented] (HBASE-4814) Starting an online alter when regions are splitting can leave their daughters unaltered
Date Mon, 08 Apr 2013 21:40:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13625858#comment-13625858

Enis Soztutar commented on HBASE-4814:
--------------------------------------

Yes, this would be fixed by table locking. See HBASE-7546 and the test in TestTableLockManager.testTableReadLock().
Should we resolve this?

> I've seen a situation where regions were splitting almost exactly at the same time as
an alter command was issued and those regions' daughters were left unaltered. It would even
seem that the daughters' daughters also share this situation.
> Reopening all the regions fixes the problem.
