Change hadoop service group post-install

[#1]

We can set the "Hadoop Group" during installation by using the customize services => Misc tab. How to change it post-install ?

[#2 · Accepted solution]

The Hadoop Group can be changed with the following command:

/var/lib/ambari-server/resources/scripts/configs.sh \
-u admin -p admin set localhost cluster_name cluster-env user_group new_group

This assumes it is running from the Ambari host with the default credentials. Replace cluster_name with the name of the cluster.
