------------------------------------------------------------------
I saw this on test cluster. Test cluster runs functional / advanced tests.
Cluster has 4 nodes. Nodes are restarted using drillbits.sh script in order to
run tests on clear env. All nodes are restarted at the same time using
{{clush}} (example: {{clush -a /drill/bin/drillbit.sh restart}}). I ran tests
on master so grace period was set 0 (the current default).
{quote}
Did you see it running even after 120 sec ?
{quote}
Yes, it did.
So there can be two options:
1. It might be the case that Drillbit was restarted (stop + start) and some how
drillbit status was not updated. Drillbit status remained in quiescent, though
drillbit was running and it mode supposed to be online. Maybe Zk missed status
update.
Or maybe
2. Drillbit was really in quiescent mode and somehow further shutdown just
hanged.

>
> After DRILL-4286 once I got a situation that after running all functional
> tests three drillbits were in ONLINE state, another one in QUIESCENT. Though
> from the one in quiescent state I could run queries and so it was online.
> drillbit.sh stop could not shutdown it and had to do kill -9 of the process
> (online_vs_quiescent.JPG).
