> Project: Accumulo

> Reporter: Eric Newton
> Assignee: Eric Newton
> Priority: Blocker
> Fix For: 1.5.3, 1.7.0, 1.6.3

> While attempting to write a test for ACCUMULO-3597, I found the master was
> not balancing. The iterator that filters the metadata table does not take
> migrations into account, so the state of the tablets was never seen, and
> processed. This bug was introduced with the fix to ACCUMULO-3580.
