    I would like to bring up an opportunity for re-use.
    with in the mapred-site.xml (for our implementation) we are using the following to allow access to mapreduce logs ...etc..
    Why reinvent the wheel, most often the users/groups for both MR and Spark would be the some or all of the same user/groups.
    My suggestion is to create a common list/set of properties between MR and Spark for acls. Instead of maintaining two separate lists
    mapreduce.cluster.acls.enabled = true
    mapreduce.job.acl-view-job=mapred,hue,* <group name>
    mapreduce.job.acl-modify-job=mapred,hue,* <group name>
