-----------------------------------
Err, I commented on
https://github.com/apache/hbase/commit/1446d01e98af2366c389676c25c74c4ce89a513a
because I think -noBalanceSwitch can race. Also, these options might be a bit
backwards. Really, we only need write locking.
> Add -noLock and -noBalanceSwitch options to hbck

> HBCK is sometimes used as a way to check the health of the cluster. When
> doing that it's not necessary to turn off the balancer. As such it's not
> needed to lock other runs of hbck out.
> We should add the --no-lock and --no-balancer command line flags.
