Nicolas Spiegelberg commented on HBASE-6143:
--------------------------------------------
The default behavior should most likely take load balancing into account (See HBASE-4191). In FB, our master has a concept of 'favored nodes' that are assigned upon Region creation and map directly to the HDFS replication pipeline.

--------------------------------------
I agree. Though sometimes choosing a balance of the regions can be an expensive operation so the balancer should provide an api for a cheap balance.
