Maja Kabiljo updated GIRAPH-756:
--------------------------------

    Attachment: GIRAPH-756.patch

There is a special zk node which master checks for and which should be created in order to halt. Created a short script which can be used to create a zk node. After running the application instructions on how to halt will be printed to terminal.

> It would be good to have a way to tell a running application to halt after current superstep is done instead of just killing it. For example, it would be useful when we have a long running application, but we need resources for another job, or we see that the result is good enough, we can just halt it and still get the output.
