oozie Authentication exception: GSSException: No valid credentials provided (Mechanism level: Failed

[Ioan123]

Hello All

I'm getting the following error with any oozie client commands

Authentication exception: GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos credentails)

 It was working well untilk a few days ago when this started.

I have a valid kerberos ticket (klist + hdfs dfs -ls / or anything but oozie work perfectly well).

Also restarted oozie, no better luck

Any ideas, I could not find anything wrong with the configuration so far

Thank you for any suggestion!

Can you please share the Oozie command that you ran? Also, any errors you can capture from the Oozie server log?

Have you also tried a few different users, like "hdfs", "oozie", "hive" etc to see if behaviours are different due to user difference?

Hello

Any oozie client command fails, the specific one I used is

oozie jobs -auth KERBEROS  -oozie https://[redacted-server-same]:11443/oozie

Any other Hadoop works perfectly (with same keytab) - for example hdfs dfs -ls / works like a charm

Thanks for your help

I was able to resolve the issue by doing the following:

- remove LB name from oozie in CM + restart oozie

- put back the LB name in oozie + restart oozie

Then it worked, it probably needed to regenerate some krb tickets

Good finding, looks like the keytab file for Oozie was outdated.
