When attempting to write a dataframe from Spark to HBase on yarn using the Spark HBase Connector. On the write stage, the jobs do not fail and will run indefinitely (one has run an entire night before I killed it in the morning), but the executors throw: “WARN AbstractRpcClient: Exception encountered while connecting to the server : javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)] ERROR AbstractRpcClient: SASL authentication failed. The most likely cause is missing or invalid credentials. Consider 'kinit'. javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)” I have a valid hashed Kerberos ticket, keytab, and conf file. Versions Spark – 1.6.2 HDP 2.5 HBase - 1.1.2.2.5.3.0-37 SHC - 1.0.0-1.6-s_2.10 Any help would be greatly appreciated 🙂 ... View more
