UserGroupInformation: No groups available for user

问题

I am trying to submit a remote job in mapreduce, but I get the error [1]. I even have set in hdfs-site.xml in the remote hadoop the content [2], and changed permissions [3], but the problem remains.

The client is xeon, and the superuser is xubuntu.

How I add a remote user permission to submit in mapreduce? How I set a group for xeon?

[2]

<property>
    <name>dfs.web.ugi</name>
    <value>xeon,webuser,webgroup</value>
</property>

[3]

2041  hdfs dfs -chown -R xeon:supergroup /user/xeon
2045  hdfs dfs -chown -R xeon:supergroup /tmp/hadoop-yarn/staging/xeon/
2039  hdfs dfs -chmod -R 777 /user/xeon
