Start TGT gen failed for user - KeytabException: unable to get keytab fileName

SimonBergerard — Tue, 21 Apr 2026 08:55:17 GMT

Hi every one,

I encountered the following error when I ran a cde cli command launching spark or airflow job.

ERROR Start TGT gen failed for user: my_user, error: rpc error: code = Internal desc = java.lang.RuntimeException: com.cloudera.thunderhead.service.tgtgenerator.services.KeytabException: unable to get keytab fileName

Have you ever seen this before?

To resolve this issue, I just ran my command again and it passed after some tries.

Does someone have a solution to pass this command at the first time?

My command seems:

cde job run --name my_job_name --variable var1=$(date +'%Y%m%d%H%M%S') --variable var2=$(date +'%Y%m%d%H%M%S') --variable var3=100 --variable var4=yyyyMMddHHmmss

Thank you

Hello @SimonBergerard

Just wanted to check the CDE version you are using and are your colleagues facing the same issue with CDE?
