Review comment:
Here is what I changed it to in coming patch...
" Do a server-side fix of bad or inconsistent state in hbase:meta.
Available in hbase 2.2.1/2.1.6 or newer versions. Master UI has
matching, new 'HBCK Report' tab that dumps reports generated by
most recent run of _catalogjanitor_ and a new 'HBCK Chore'. It
is critical that hbase:meta first be made healthy before making
any other repairs. Fixes 'holes', 'overlaps', etc., creating
(empty) region directories in HDFS to match regions added to
hbase:meta. Command is NOT the same as the old _hbck1_ command
named similarily. Works against the reports generated by the last
catalog_janitor and hbck chore runs. If nothing to fix, run is a
noop. Otherwise, if 'HBCK Report' UI reports problems, a run of
fixMeta will clear up hbase:meta issues. See 'HBase HBCK' UI
for how to generate new report.
