Jim Kellerman updated HADOOP-1678:
----------------------------------
Fix Version/s: 0.15.0
Affects Version/s: 0.15.0
Status: Patch Available (was: Open)
While server reassignment worked for server failure when n=1 and one new server
replaced the failed server, testing for this patch revealed a bug when there
were multiple region servers. This patch also addresses this bug.
> [hbase] On region split, master should designate which host should serve

> On region split, the daughter regions are deployed on the same host as served
> the split parent. This makes it so currently (unless the cluster is
> restarted), as a table grows, all its regions remain on the one server.
> Instead, jurisdiction over who serves daughter splits should be passed to the
> master. If possible, before making a determination, the master should take
> into consideration current cluster loadings and region distribution.
