Subject [jira] Updated: (HADOOP-2138) [hbase] Master should allocate regions to the regionserver hosting the region data where possible
Date Sat, 08 Dec 2007 06:39:43 GMT

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.

> 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.
