      Description

      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.
