stack updated HBASE-2819:
-------------------------

    Attachment: 2819-v14.txt

Found a few issues in RPC trying to make a basic unit tests where I run hbck in unit test context.   The QoS stuff in HRegionServer presumed all invocations had an argument (getOnlineRegions has no param) and then getOnlineRegions returned a NavigableSet which we can't handle in HBaseObjectWritable.

Upped the RPC version number again. This probably means REST will fail again up on hudson -- because I believe there is an old server running across tests -- but will deal with that in a different issue.

Fixed HBaseFsck so it scans -ROOT-... was broke the way it was written.

HBaseAdmin has handling of null HRegionInfo.

All of above based on the last patch Jon posted to review.hbase.org.

> Right now, the hbck utility can detect issues with region deployment but can't fix them.
> It should be able to handle basic things like closing one side of a double assignment, re-adding something to META, etc.
