[hbase] Master should allocate regions to the regionserver hosting the region data where possible
-------------------------------------------------------------------------------------------------

                 Key: HADOOP-2138
                 URL: https://issues.apache.org/jira/browse/HADOOP-2138
             Project: Hadoop
          Issue Type: Improvement
          Components: contrib/hbase
            Reporter: stack
            Priority: Minor


Currently, regions are assigned regionservers based off a basic loading attribute.  A factor
to include in the assignment calcuation is the location of the region in hdfs; i.e. servers
hosting region replicas.  If the cluster is such that regionservers are being run on the same
nodes as those running hdfs, then ideally the regionserver for a particular region should
be running on the same server as hosts a region replica.
