Ramya Sunil commented on MAPREDUCE-3819:
----------------------------------------
bq. How easy is this to reproduce? Do I just need to start running map/reduce
jobs, and it starts to show up eventually? Do these need to be long running
jobs?
You just need to start MR jobs and it starts showing up. They dont need to be
long running.
bq. Could you please verify that the following is set in your resource manager
configuration "dfs.namenode.kerberos.principal"
Verified and it is correctly set in the RM configs.
