Alexander Georgiev updated HBASE-2819:
--------------------------------------

    Attachment: HBASE-2819.patch

This patch is for the 0.89 branch, adding functionality to HBase FSCK (HBCK) to fix some of the common issues that may arise while running HBase.
New features are:
  - Added -fix option, which tries to repair duplicate assignments or unassigned regions in META.
  - Check if META and ROOT are good before starting the usual check process.
  - Check table consistency - if there are missing or overlapping regions
  - Added option for quiet run, which doesn't print most of the information
  - Added printing of summary of the check - number of tables, per-table number of regions, which tables are consistent and which are not and so on.

It uses a RPC call which is no longer available after the master rewrite, so it might take some time to integrate. We are currently working on that.

> 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.
