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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
