Keith Turner commented on ACCUMULO-3480:
----------------------------------------

Wow, it seems like the switch from TreeMap to HashMap made a bigger difference for your test
case than mine.

For your test case how long does the call to balance take when everything is already balanced?

> 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.
