abhishek bafna updated OOZIE-2531: ---------------------------------- Fix Version/s: (was: trunk) 4.3.0 > Prevent Spark trying for token which is already available > ---------------------------------------------------------- > > Key: OOZIE-2531 > URL: https://issues.apache.org/jira/browse/OOZIE-2531 > Project: Oozie > Issue Type: Improvement > Reporter: Satish Subhashrao Saley > Assignee: Satish Subhashrao Saley > Fix For: 4.3.0 > > Attachments: OOZIE-2531-1.patch, OOZIE-2531-2.patch > > > As per [Apache Spark > documentation|http://spark.apache.org/docs/latest/running-on-yarn.html#spark-properties] > : > The property {{spark.yarn.security.tokens.service.enabled}} in Apache Spark > which controls whether to retrieve delegation tokens for non-HDFS services > when security is enabled. By default, delegation tokens for all supported > services are retrieved when those services are configured, but it's possible > to disable that behavior if it somehow conflicts with the application being > run. > Currently supported services are: hive, hbase > It would be good to have default as > {{spark.yarn.security.tokens.hive.enabled=false}} to avoid having Spark > redundantly retry obtaining a token when it already has one (passed > originally from Oozie's hcat credentials). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
