Eric Newton resolved ACCUMULO-3580.
-----------------------------------
    Resolution: Fixed

I've disabled the optimized read of the metadata table in 1.5 and 1.6. Fixed and turned on
the optimization in 1.7.

> I was examining -Xlint warnings and found this warning about a fall-through case in a
switch statement:
> The {{TabletStateChangeIterator}} in the master does not properly skip over tablets which
are hosted and online and have no work to do. This probably makes the master handle these
when it doesn't need to.
