> See HBase-TRUNK build #1820
> This could be due to HBASE-3681
> In trunk, default value of "hbase.regions.slop" is 20%. It is possible for load balancer
to see region distribution which falls within 20% of optimal distribution.
> However, assertRegionsAreBalanced() uses 10% slop.
> One solution is to align the slop in assertRegionsAreBalanced() with "hbase.regions.slop"
value.
