Description

The first time I tried running hello-samza's bin/grid script, the script exited with a "no such file or directory" when trying to invoke the yarn-daemon.sh scripts in stop_yarn() because $DEPLOY_ROOT_DIR/yarn does not exist since the script tries to stop the service before installing them.

The fix is trivial: surround the two invocations with a check to see whether they exist, similar to the other stop_* functions.

If this is not because I am running the script incorrectly, I can go ahead and post the patch that fixes this.
