Xu Cang commented on HBASE-22642: --------------------------------- [~Xiaolin Ha] Thanks! I re-reviewed the patch. Looks good. But there is one unit test's still failing. Could you please take a look? thanks > Make move operations of RSGroup idempotent > ------------------------------------------ > > Key: HBASE-22642 > URL: https://issues.apache.org/jira/browse/HBASE-22642 > Project: HBase > Issue Type: Bug > Components: rsgroup > Reporter: Xiaolin Ha > Assignee: Xiaolin Ha > Priority: Major > > Currently, when moving tables or servers to a group, only groupInfo is > checked. And in RSGroup implementation, groupinfo is written to disk before > regions movements are done. If there are some problems caused move regions > abort, some regions will be on wrong regionservers. What's the worse, retry > the move operation will be rejected because of the correct groupinfo. > We think when moving, not only groupInfo should be checked, but also relevant > region assignments should be checked and corrected. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
