Shabab, I think so, but the Hadoop’s site says |The user@ mailing list
is the preferred mailing list for end-user questions and discussion.|So
I am using the right mailing list.
Back to my problem, I think that this is a problem about HDFS security.
But the strangest thing is that I have disabled it in |hdfs-site.xml| [1].
I think that this error happens when MapReduce is trying to write the
job configuration files in HDFS.
I have set the username of the remote client in the mapreduce using the
commands in [2].
Now, I am looking to the Netflix Geni to figure it out how they do it,
but right now I still haven’t found a solution to submit a remote job
using Java. If anyone have a hint, or advice, please tell me. I really
don’t understand why I get this error.

|$ cat etc/hadoop/hdfs-site.xml

In Namenode host.
$ sudo adduser xeon
$ sudo adduser xeon ubuntu

Hi,
I am trying to submit a remote job in Yarn MapReduce, but I
can’t because I get the error [1]. I don’t have more
exceptions in the other logs.
My Mapreduce runtime have 1 /ResourceManager/ and 3
/NodeManagers/, and the HDFS is running properly (all nodes
are alive).
I have looked to all logs, and I still don’t understand why I
get this error. Any help to fix this? Is it a problem of the
remote job that I am submitting?
