----------------------------------------------------------------
Andrew, looks good. I'm going to wait for the hadoopqa robot to execute the
test suite. Alternately, since this just modifies hbck, can you try this
command and share results: 'mvn test -PlocalTests -Dtest=TestHBaseFsck'?
I'd like to keep all hbck across versions essentially the same -- would you be
willing to port to 0.90/0.92/0.94? I'd bet that this may apply to 0.94 and
0.92, and that 0.90 would require some near trivial tweaks.

> This would convert WorkItem* logic (with low level notifies, and rough
> exception handling) into a more canonical Futures pattern.
> Currently there are two instances of this pattern (for loading hdfs dirs, for
> contacting regionservers for assignments, and soon -- for loading hdfs
> .regioninfo files).
