NullPointerException: JobTracker.resolveAndAddToTopology - Failed to run Job on new hadoop 2.0.0 (CDH4.51)
After a new installation of CDH4.51 (Hadoop 2.0.0) we get this exception
when trying to run a job. We have not done any configuration of rack
awareness (everything is in /default).
Job initialization failed:
java.lang.NullPointerException

This bug looked related, but we couldn't work out a solution from the
comments:
https://issues.apache.org/jira/browse/MAPREDUCE-50
Any ideas?
Thanks,
