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
> Mpack uses wrong group for owning HDFS directories

> The group got changed a bit ago from cluster_env.user_group (hadoop) to
> cluster_env.metron_group (metron). However, because everything right now
> runs as the storm user (which is in the hadoop group), it doesn't have perms
> to write anymore.
