Jean-Daniel Cryans commented on HBASE-1921:
-------------------------------------------
Well in this case it's a different solution I have in mind. For sure, cleanly
restarting the processes would be nice and would solve this problem but what I
was thinking is that when the master loses its session, it should try to re-get
the lock right away (no restart). This way you keep the internal state and if
no other master took its place, then it's a win. Else, harakiri.
