Review comment:
I'm good w/ this. Just need to watch it.
I've added changes and then found I sometimes made the situation worse. Need
to watch out for that here but it is HBCKSCP, run by the operator, so they
should be looking at the result when manually running hbck2.

Review comment:
Yeah... it seems but the compare to RSN fails so we don't clean the
unknown server... ok. Got it.

Review comment:
Is it that the RSN is null but hbase:meta is an 'unknown server'?
