-------------------------------------
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.
