Vinod Kumar Vavilapalli reopened YARN-2131:
-------------------------------------------
Reopening for the addendum..
One other thing that occurred to me was running RM while the format is in
progress or vice-versa. Namenode solves this issue by a lock file. We can do
the same here.
Irrespective of the approach, I think handling the above is a major blocker for
this feature/patch. Let's try to do that here too..

> there is no easy way to do this and users should understand how each store
