stack commented on HBASE-2691:
------------------------------
.bq What about ServerAlreadyExistingException and
ServerAlreadyConsideredDeadException? (I'm not good at naming stuff)
Doing above and purging LeaseStillHeldException as you suggest is a good idea.
It solves differentiating the different startup/dead-server circumstances.
Regards naming, they ain't too bad. The latter could be YouAreDeadException
(with its message holding info on why its considered dead). The former could
be PleaseHoldException (its message would be why the holdup).
> LeaseStillHeldException totally ignored by RS, wrongly named

> Then it will retry until the watch is triggered telling it that the session's
> expired! Instead, we should be a lot more proactive initiate abort procedure.
