Bryan Duxbury updated HADOOP-2138:
----------------------------------
Priority: Major (was: Minor)
This seems like it should be an important issue, since it should significantly
improve the performance of the cluster (faster, less network traffic).
Elevating to Major.
> [hbase] Master should allocate regions to the regionserver hosting the region
> data where possible

> 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.
