Wenchen Fan resolved SPARK-21369. --------------------------------- Resolution: Fixed Fix Version/s: 2.3.0 2.2.1 Issue resolved by pull request 18593 [https://github.com/apache/spark/pull/18593] > Don't use Scala classes in external shuffle service > --------------------------------------------------- > > Key: SPARK-21369 > URL: https://issues.apache.org/jira/browse/SPARK-21369 > Project: Spark > Issue Type: Bug > Components: Shuffle, YARN > Affects Versions: 2.2.0 > Reporter: Shixiong Zhu > Assignee: Shixiong Zhu > Fix For: 2.2.1, 2.3.0 > > > Right now the external shuffle service uses Scala Tuple2. However, the Scala > library won't be shaded into the yarn shuffle assembly jar. Then when the > codes are called, it will throw ClassNotFoundException. > Right now it's safe because we disabled spark.reducer.maxReqSizeShuffleToMem > by default. However, to allow using spark.reducer.maxReqSizeShuffleToMem for > Yarn users, we should remove all usages of Tuples. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
