Failed to start MapReduce job. Please consult search.log

Running into an issue with Hunk against our Kerberized, YARN cluster. The Hunk principal auth works fine, what ends up happening is that a search will kick off, start searching thru events returns some results and previews: but after running over ~1 minute, it dies with:

01-27-2014 18:56:39.021 ERROR ERP.redacted-provider -  UserGroupInformation - PriviledgedActionException 
as:hunk@REDACTED.COM (auth:KERBEROS) cause:javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7) - UNKNOWN_SERVER)]

the following error message is thrown in the UI too

[redacted-provider] JobStartException - Failed to start MapReduce job. Please consult search.log for more information. Message: [ Failed to start MapReduce job, name=SPLK_search1.dev.hunk.redacted.com_1390848963.3_0 ] and [ null ]

Any pointers would be appreciated

The root cause of the above problem was a typo in the service principal specification for the resourcemananager principal

vix.yarn.resourcemanager.principal = yarn/namenode.redacted.com@REDACTED.COM

a change to the generic/wildcard principal specification fixed the issue

vix.yarn.resourcemanager.principal = yarn/_HOST@REDACTED.COM
