Apache Spark reassigned SPARK-17209: ------------------------------------ Assignee: Apache Spark > 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 > Assignee: Apache Spark > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
