Andrew Purtell commented on HBASE-12891:
----------------------------------------
bq. should not we rethrow the exception, rather than just printing a log for
it. It changes the behavior for hbck where it used to throw the exception.
I think if that's a concern we could make the change in a quick followup
> Parallel execution for Hbck checkRegionConsistency
