[jira] [Commented] (HBASE-9080) Retain assignment should be used
when re-enabling table(s)
[ https://issues.apache.org/jira/browse/HBASE-9080?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13723329#comment-13723329 ]
Lars Hofhansl commented on HBASE-9080:
--------------------------------------
+1 on v3 on HBASE-6143.
[~jxiang], [~stack], is the BulkAssigner is unsafe in 0.94? Should we remove the enabled.roundrobin from 0.94?

> Key: HBASE-9080
> URL: https://issues.apache.org/jira/browse/HBASE-9080
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.10
> Reporter: Ted Yu
> Assignee: Ted Yu
> Fix For: 0.94.11
>
>
> Region servers are picked in round robin fashion when a table is re-enabled.
> This results in poor data locality.
> We should use retain assignment when re-enabling table(s).
> For initial discussion, see HBASE-6143
> Since patches for 0.94 and trunk may turn out to be very different, this JIRA is for fixing the issue in 0.94 branch.
> Thanks Lars, Elliot, Vladmir and Stack for providing opinions on this subject.
