--------------------------------
Summary: Support manual credential updating in the run-time for Spark on
YARN (was: Support manual credential updating in the run-time)
> Support manual credential updating in the run-time for Spark on YARN
> --------------------------------------------------------------------
>
> 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 works of SPARK-14743.
