Subject Oozie distcp failed in secure cluster
Date Fri, 29 Jul 2016 07:23:27 GMT
Hi,

I have configured hadoop-2.7.2 and oozie-4.2.0 with Kerberos security
enabled.

Distcp oozie action submitted as workflow job. When running the oozie
launcher, i am getting following exception.

How to resolve the error?

Delegation Token can be issued only with kerberos or web authentication

Need help to resolve it.


Thanks,

Kumar
