[jira] [Reopened] (HBASE-10184) [Online Schema Change]: Add additional tests for online schema change

["Andrew Purtell (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-10184?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Purtell reopened HBASE-10184:
------------------------------------


The changes passed a precommit build and locally, but have failed in more than one trunk and 0.98 build up on Jenkins and recently in a precommit build there as well. 

I will revert this from 0.98 now.

[~aleksshulman], the failures may be tests working as intended, revealing issues with online schema change. If you are interested in debugging the failures on trunk, we can leave this committed there for a bit (unless objection) to facilitate that.
