Jonathan Gray commented on HBASE-3280:
--------------------------------------
Somewhat related to this, what happened on a cluster here is that the HRS got
stuck in this loop trying to reconnect to master and ignoring the
YouAreDeadExceptions. But then once the master finished shutdown handling, it
removes this server from the dead server list. Then the RS actually
successfully heartbeated in to the master and the master thought it was a legit
RS (even though it just finished doing a shutdown of it).
Is there a reason we should ever clear things out of the dead server list? If
this RS is in a network partition it may not check back with the master for a
long time so we should always remember the dead serverNames (which include
start codes)?

> In the HRS, when we lose our connection to the master, we enter into a loop
> where we keep trying to get the new master location in ZK and attempt to send
> our heartbeat. Within tryRegionServerReport() we could get a
> YouAreDeadException, but we won't let it out. This leads to the RS
> continuously heartbeating in to the master although the master keeps telling
> it to kill itself.
