> --------------------------------------------------------------------
>
> Key: SPARK-17209
> URL: https://issues.apache.org/jira/browse/SPARK-17209
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core, YARN
> Reporter: Saisai Shao
> Priority: Minor

> Current Spark on YARN supports time based credential renewal and updating, this mainly addresses the problem of token expiration for long running Spark applications.
> But still there're some use cases in which security services will be changed in the run-time of Spark application. For example, user may want to change to access another HBase cluster or Hive Metastore service in the run-time, in such use cases credentials should be updated immediately by user explicitly, so that user could reconnect to new HBase cluster or Metastore service.
> So here propose to add ability in Spark to manually trigger the credential updating in the run-time.
> This is a follow-up work of SPARK-14743.
