-------------------------------------

             Summary: SparkClientImpl should pass principal and keytab to spark-submit instead
of calling kinit explicitely
                 Key: HIVE-14383
                 URL: https://issues.apache.org/jira/browse/HIVE-14383
             Project: Hive
          Issue Type: Improvement
          Components: Spark
    Affects Versions: 2.1.0
            Reporter: Mubashir Kazia


In https://github.com/apache/hive/blob/master/spark-client/src/main/java/org/apache/hive/spark/client/SparkClientImpl.java#L331,
kinit is manually called before spark-submit is called. This is problematic if the spark session
outlives the delegation token expiry period or the kerberos ticket expiry period. A better
way to handle this would be to pass the keytab file location and principal name as parameters
to the spark-submit command when kerberos auth is in use.
