Hi, I am running spark job on yarn in cluster mode in secured cluster. I am trying to run Spark on Hbase using Phoenix, but Spark executors are unable to get hbase connection using phoenix. I am running knit command to get the ticket before starting the job and also keytab file and principal are correctly specified in connection URL. But still spark job on each node throws below error:
15/12/01 03:23:15 ERROR ipc.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)] at com.sun.security.sasl.gsskerb.GssKrb5Client.evaluateChallenge(GssKrb5Client.java:212) I am using Spark 1.3.1, Hbase 1.0.0, Phoenix 4.3. I am able to run Spark on Hbase(without phoenix) successfully in yarn-client mode as mentioned in this link: https://github.com/cloudera-labs/SparkOnHBase#scan-that-works-on-kerberos Also, I found that there is a known issue for yarn-cluster mode for Spark 1.3.1 version: https://issues.apache.org/jira/browse/SPARK-6918 Has anybody been successful in running Spark on hbase using Phoenix in yarn cluster or client mode?
