[hbase] On region split, master should designate which host should serve
daughter splits
----------------------------------------------------------------------------------------
Key: HADOOP-1678
URL: https://issues.apache.org/jira/browse/HADOOP-1678
Project: Hadoop
Issue Type: Bug
Components: contrib/hbase
Reporter: stack
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.
