> 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.
