> The flume stop script does the following:
> kill -TERM ${FLUME_PID} &>/dev/null
> sleep 5
> kill -KILL ${FLUME_PID} &>/dev/null
> It is not recommended to kill -9 flume while it is shutting down.
> The correct approach is to poll to see if the pid is up every second or so,
> after sending the intitial TERM signal, then after some long period of time
> (60 seconds) if the pid is still alive then kill -9 would be appropriate.
