Robert Joseph Evans commented on MAPREDUCE-3819:
------------------------------------------------
Sorry I have been dealing with other things that have come up, and only now was
I able to get back to this issue.
I have added some debug statements to the Security Utils, and indeed the config
option dfs.namenode.kerberos.principal is coming back as null. This does not
mean that it is not set. I grepped through the configs and found it set in
hdfs-site.xml. I need to see if there is something about the RM that it is not
loading this resource, or what.
