Apache Spark commented on SPARK-24149: -------------------------------------- User 'wangyum' has created a pull request for this issue: https://github.com/apache/spark/pull/21734 > Automatic namespaces discovery in HDFS federation > ------------------------------------------------- > > Key: SPARK-24149 > URL: https://issues.apache.org/jira/browse/SPARK-24149 > Project: Spark > Issue Type: Improvement > Components: YARN > Affects Versions: 2.4.0 > Reporter: Marco Gaido > Assignee: Marco Gaido > Priority: Minor > Fix For: 2.4.0 > > > Hadoop 3 introduced HDFS federation. > Spark fails to write on different namespaces when Hadoop federation is turned > on and the cluster is secure. This happens because Spark looks for the > delegation token only for the defaultFS configured and not for all the > available namespaces. A workaround is the usage of the property > {{spark.yarn.access.hadoopFileSystems}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
