Test steps:

[[email protected] hadoop-yarn]# sudo su - -c "groupadd testUser5" root
[[email protected] hadoop-yarn]# sudo su - -c "useradd testUser5 -g testUser5" root
[[email protected] hadoop-yarn]# sudo su - -c "groupadd Group5" root
[[email protected] hadoop-yarn]# sudo su - -c "usermod -a -G Group5 testUser5" root
[[email protected] hadoop-yarn]# groups testUser5
testUser5 : testUser5 Group5
[[email protected] hadoop-yarn]# sudo su - -c "yarn rmadmin

[[email protected] hadoop-yarn]# sudo su - -c "yarn rmadmin -getGroups testUser5"
yarn
testUser5 : testUser5 Group5
[[email protected] hadoop-yarn]# sudo su - -c "gpasswd -d testUser5 Group5" root
Removing user testUser5 from group Group5
[[email protected] hadoop-yarn]# groups testUser5
testUser5 : testUser5
[[email protected] hadoop-yarn]# sudo su - -c "yarn rmadmin
-refreshUserToGroupsMappings" yarn
[[email protected] hadoop-yarn]# sudo su - -c "yarn rmadmin -getGroups testUser5"
yarn
testUser5 : testUser5{noformat}
In Summary, *sudo su - -c "/usr/hdp/current/hadoop-yarn-client/bin/yarn rmadmin
-getGroups testUser5" yarn* and *groups testUser5* gives same o/p.
[~leftnoteasy] pls help to review the patch. We also had to make change in
AdminService.java in addition to RM init call.
