Saisai Shao reassigned SPARK-23635: ----------------------------------- Assignee: Saisai Shao > Spark executor env variable is overwritten by same name AM env variable > ----------------------------------------------------------------------- > > Key: SPARK-23635 > URL: https://issues.apache.org/jira/browse/SPARK-23635 > Project: Spark > Issue Type: Bug > Components: YARN > Affects Versions: 2.3.0 > Reporter: Saisai Shao > Assignee: Saisai Shao > Priority: Minor > > In the current Spark on YARN code, AM always will copy and overwrite its env > variables to executors, so we cannot set different values for executors. > To reproduce issue, user could start spark-shell like: > {code:java} > ./bin/spark-shell --master yarn-client --conf > spark.executorEnv.SPARK_ABC=executor_val --conf > spark.yarn.appMasterEnv.SPARK_ABC=am_val > {code} > Then check executor env variables by > {code:java} > sc.parallelize(1 to 1).flatMap \{ i => sys.env.toSeq > }.collect.foreach(println) > {code} > You will always get {{am_val}} instead of {{executor_val}}. So we should not > let AM to overwrite specifically set executor env variables. -- 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
