That's unusual. Are you able to submit a simple sleep job? You can do this
using:
yarn jar
$HADOOP_PREFIX/share/hadoop/mapreduce/hadoop-mapreduce-client-jobclient-*-tests.jar
sleep -m 1 -r 1
This should finish it in under a minute. Otherwise I'd suspect that your
cluster is misconfigured.

Hi,
I have submitted a mapreduce job, and can find it from job list, however I
find its STATE is PREP over last 8 hours, any idea why it takes so long to
"PREP"?
