Sebastian Bauer commented on HBASE-3507:
----------------------------------------

@Ted Yu: maybe average from all regionservers requests counters and if regionserver diverge from this average(+/- some percent) we move region that leverage this?


@rayan rawson: this was needed only once after hadoop big crash when hbase cannot reassign regions to the same regionservers. In this form rebalance is not for frequently use
