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?
