--- End diff --
On a single node env (with HMaster, RegionServer, Zookeeper in a single
process), I saw instances where the HMaster would get stuck at startup.
Restarting HBase multiple times wouldn't help but executing 'hbase hbck
-repair' somehow took care of the issue. I am not sure what it cleaned up in
the HBase space.
So, I wrapped this in a little script. Currently, I would not suggest that
'ilh_hbase_repair' be used in a clustered/production env by itself.
