Can you try what Samir suggests? Can replay moved-aside logs using
WALPlayer after cluster comes up.

I see that at first we are making progress through the WALs ("... total
tasks = 7..." ... it was 9 in your master log) but maybe they are getting
stuck on particular WALs.  The stuck Master has same task list over last 24
hours?

On the RS log, I see you are stuck trying to recover 1453728374800

We are trying to recover the lease on the file from NN. Below looks bad.
Over a minute and still not lease recovery.

   4%2C1452811286456.default.1453728374800 after 68218ms

NN showing us stuck on lease recovery?

NN went down during power outage?

The BadVersion is probably because task has been assumed by another because
lease recovery taking too long.

I see 1453728374800 is still in the list you paste from Master later in
this thread.

Try moving it aside. Might have to restart master for it to notice the
move-aside... Try not restarting first.
