Hi, I tried to build a small app all under Kerberos.
JDBC to Phoenix works Client to HBase works Client (puts) on Spark to HBase works. But JDBC on Spark to HBase fails with a message like "GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]" Keytab is accessible on all the nodes. Keytab belongs to the user running the job, and executors are running under that user name. So this is fine. Any idea of that this might be? Thanks, JMS
