    please put this line in the `hadoop params` section (circa line 80).
    
    Also, why equate hadoop_group to 'user_group'?  In typical hadoop deployments there is
already a group named 'hadoop'.  It is managed by Ambari.  In a recent test install of HDP+Metron,
it was defined as follows (from /etc/group), which I think would meet your intended use since
both storm and metron are included:
    * hadoop: x :1004:hive,storm,zookeeper,infra-solr,zeppelin,metron,livy,elasticsearch,spark,flume,kafka,hdfs,yarn,kibana,mapred,hbase,hcat
