@jsensharma Could you explain a little more about what exactly this 

hadoop.proxyuser.root.groups

config is? Any docs describing it more?

Hi,

``You can configure proxy user using properties hadoop.proxyuser.$superuser.hosts along with either or both of hadoop.proxyuser.$superuser.groups and hadoop.proxyuser.$superuser.users.``
