Christopher Tubbs commented on ACCUMULO-925:
--------------------------------------------
Might be good to make accumulo_watcher.sh (ACCUMULO-3569) script use this PID
file instead of it's currently monitoring the *.out *.err files.
> Launch scripts should use a PIDfile

> Start scripts should create PIDfiles to store the PID of running processes in
> a well known location (example: /var/run/accumulo/tserver.pid or
> $ACCUMULO_HOME/tserver.pid), for the following benefits:
> # Identify running services on a machine without executing and parsing the
> system process list, so stop scripts can kill them when they are unresponsive.
> # Prevent multiple instances of the same application from starting up (an
> environment variable for the location of the PIDfile can be used to allow
> multiple instances if it is desirable to do so).
> # Potentially provide an alternate mechanism for terminating a process by
> deleting its PIDfile rather than its lock in Zookeeper.
