Josh Elser commented on ACCUMULO-3601:
--------------------------------------
{code}
+ @Override
+ public Collection<KeyExtent> migrations() {
+ return migrations.keySet();
+ }
{code}
Looking at this, I think this is incorrect. This will return the keyset, but
iteration over that keyset is only safe when synchronizing on the original
migrations object.
> 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.
