Adrian Bridgett created SPARK-11653:
---------------------------------------

             Summary: Would be very useful if spark-daemon.sh supported 
foreground operations
                 Key: SPARK-11653
                 URL: https://issues.apache.org/jira/browse/SPARK-11653
             Project: Spark
          Issue Type: Improvement
          Components: Deploy
    Affects Versions: 1.5.1
            Reporter: Adrian Bridgett
            Priority: Minor


See also SPARK-5964.  I've raised a new ticket for a few reasons:
- alternative more minimal patch (I've not submitted a PR as I thought any 
discussion would be better here): 
https://github.com/abridgett/spark/tree/feature/add_spark_daemon_foreground
- couldn't re-open the original ticket and didn't know if a comment would 
suffice

There are quite a few use cases for this, e.g. when running under Mesos the 
shuffle service needs to be running and trying to do this under Marathon is a 
bit painful without this feature.  

I see that there was a plan for these scripts to be rewritten in Python, 
however until then this would be very useful (and can feed into the rewrite as 
well).
