Karan Mehta commented on HBASE-18228:
-------------------------------------
bq. Also, curious, why branch 1.3 specifically?
I will submit a patch for branch-1 as well. It's just that I started working
with this branch and the scope is limited to 1.4 anyways for this patch.

> We just had a prod issue and running HBCK the way we did actually causes more
> problems.
> In part HBCK did stuff we did not expect, in part we had little visibility
> into what HBCK was doing, and in part the logging was confusing.
> I'm proposing 2 improvements:
> 1. A dry-run mode. Run, and just list what would have been done.
> 2. An interactive mode. Run, and for each action request Y/N user input. So
> that a user can opt-out of stuff.
> [~jmhsieh], FYI
