Subject One time Kerberos exception on secured Hadoop cluster
Date Fri, 27 Feb 2015 03:30:25 GMT
On a kerberos based Hadoop cluster, a kinit is done and then oozie command
is executed. This works every time (thus no setup issues), except once it
failed with following error.

Error: AUTHENTICATION : Could not authenticate, GSSException: No valid
credentials provided (Mechanism level: Generic error (description in
e-text) (60) - PROCESS_TGS).

Any thoughts on what could cause the transient failure? Would any updates
on node (e.g. Java etc.) cause such issue ?

Cluster is working fine with kerberos.
