UserGroupInformation: there are no user-accessible groups for groups

I am trying to submit a remote job to mapreduce but I am getting an error [1]. I even set content [2] in hdfs-site.xml in remote chaos and changed permissions [3], but the problem persists.

The client is xeon and the superuser is xubuntu.

How can I add permission for the remote user to mapreduce? How did I set up the group for xeon?
