Subject Re: MapReduce Job State: PREP over 8 hours, state no change
Date Mon, 08 Aug 2016 17:37:05 GMT
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.
