KERBEROS issues - HDFS cluster

Hi ,

We’ve implemented Kerberos in our hadoop cluster, but we are having issues with our pipelines.
We are getting this error 🙂

"Reason:
org.apache.hadoop.security.AccessControlException: SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS] "

“Caused by: java.util.concurrent.ExecutionException: org.apache.hadoop.security.AccessControlException: SIMPLE authentication is not enabled. Available:[TOKEN, KERBEROS]

All was configured correctly , keytabs are ok, i’m able to do a kinit from any groundplex nodes, time on KDC servers and kerberos clients is synced.
Pipelines worked ok for some while, but we saw that after we restarted jcc process on the groundplex nodes pipelines started to fail. JCE extension was installed as per https://docs-snaplogic.atlassian.net/wiki/spaces/SD/pages/2015960/How+to+Configure+a+Groundplex+for+...

Any ideas ?

Thank you,
Petrica

I’ve contacted Snaplogic support. Not even they are not able to fix the issue. 😀
