Re: regions are not getting distributed
I found the following from master log:

2013-08-23 19:23:12,791 INFO org.apache.hadoop.hbase.master.LoadBalancer:
Calculated a load balance in 24ms. Moving 2 regions off of 1 overloaded
servers onto 1 less loaded servers

Then:

Can you check region server log for vamshi_RS to see why the region failed
to open ?
