Eric Newton commented on ACCUMULO-3601:
---------------------------------------

There's very little harm in letting the master knowing the status of a tablet.

Let's say we have a migration that intersects with a table delete.  Let the 
master handle the conflict.




> master does not process migrations

> 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.
