stack updated HBASE-21378:
--------------------------
Release Note:
Adds a general -s,--skip option to hbck2 so you can run the command it first
checking it is version compatible.
Should not be needed going forward but in the spirt of our not knowing all the
conditions under which we'll be trying to run hbck2, adding it.
> [hbck2] add --skip version check to hbck2 tool (checkHBCKSupport blocks
> assigning hbase:meta or hbase:namespace when master is not initialized)
