Hi, I got into very similar issue. Did you find a way to run shell with kerberos principal. We are trying to do the same, wrap the sqoop script inside shell and use ExecuteProcess processor. It fails to execute with GSS credentials exception.
We tried to start the nifi service with 'nifi' user that has nifi service principal. We want nifi to use user kerberos principal while running this sqoop script.
Any thoughts?
