UndeclaredThrowableException when running mapreduce or spark for a specific user

Running into below error on a secure cluster with KMS configured. Surprising part is that this exception comes only for one user who is no different from other users not running into this. Any thoughts on when this error can occur ?

Most likely this is https://issues.apache.org/jira/browse/RANGER-863. The user that has issues I would bet has a lot of AD groups and has a large Kerberos request header.

Yes. That is the issue. This has been resolved based on that, but I haven't updated the question with this answer. Thanks for answering this.
