Brian Loss commented on ACCUMULO-3480:
--------------------------------------

The numbers are looking better.  Now, my big test takes about 20s and here are 
the numbers:
{noformat}
balance                            88% (17000ms)
    balanceExtraExpected           67% (12900ms)
        ColumnKeySet.removeAll     66% (12650ms)  (this is the Guava table's 
ColumnKeySet)
{noformat}

> [~bfloss] made the following comment on ACCUMULO-3439
> bq. The balance method in GroupBalancer does nothing if there are any 
> incoming migrations. You probably want to check the incoming migrations and 
> only bail out if any of those migrations are for the specific table that the 
> GroupBalancer is managing.
> I chatted w/ Brian and he also mentioned that the group balancer should 
> record time at the end, and not the beginning.
