Subject HDFS data locality
Date Tue, 17 Nov 2009 22:43:58 GMT
Hi,

When HMaster assigns regions to region servers does it try to ensure that
these files will be located on the same host in HDFS? It does not, does not
it?
So most likely HBase RegionServers are very chatty over the network, reading
and writing from/to the HDFS daemons on other nodes.

Is there a way to improve it? To make RegionServer mostly talk to the local
DataNode only?
