Jimmy Xiang commented on HBASE-9080:
------------------------------------

For 0.94, bulk assigner is not as safe as in trunk as I know.

>          Issue Type: Bug
>    Affects Versions: 0.94.10

> 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.
