STORM-1516 Fixed issue in writing pids with distributed cluster mode.
Whenever a topology is submitted, it creates respective workers on
supervisor/s. These worker pids are stored as files in
${storm-localdir}/workers/{worker-id}/pids/ on supervisor. But there is an
issue in storing worker pids. So, supervisor could not find respective worker
pids when a topology is killed. Subsequent topology deployment workers are
failed because of earlier workers are still alive and bound to the respective
ports.
Fixed worker.clj to have right checks while writing pids to respective
locations.
