Master requested tablet server halt
Hey all,
Do you know why the Accumulo Master would request the TabletServer to halt?
On the tabletserver I just saw this exception:
Master requested tablet server halt

I don't think so. It could be any number of different types of
Exceptions (UnknownHostException or ConnectException come to mind).
It was only a guess on my part -- the logs are much better than me in
that regard :)

Thanks! I will peruse the master logs. Is there a timeout that I can try
tinkering with to see if it might be a network issue?

The master will attempt to stop a TabletServer once it fails to get the
status from that server 3 times (a simple RPC). You should see some more
explanation WRT the actual Exceptions that lead to the Master requesting
the stop from the TabletServer in the Master's log.
During normal shutdown, the master will also ask TabletServers to stop,
but I imagine that isn't the situation :)
