Marcelo Vanzin commented on SPARK-21728: ---------------------------------------- Can you share your whole command line? I just added this to my {{conf/log4j.properties}}: {noformat} log4j.logger.org.apache.spark.deploy=DEBUG {noformat} And ran: {noformat} ./bin/spark-shell --master 'local-cluster[1,1,1024]' {noformat} And I see the log messages that I could not see without the custom setting. > Allow SparkSubmit to use logging > -------------------------------- > > Key: SPARK-21728 > URL: https://issues.apache.org/jira/browse/SPARK-21728 > Project: Spark > Issue Type: Improvement > Components: Spark Core > Affects Versions: 2.3.0 > Reporter: Marcelo Vanzin > Assignee: Marcelo Vanzin > Priority: Minor > Fix For: 2.3.0 > > > Currently, code in {{SparkSubmit}} cannot call classes or methods that > initialize the Spark {{Logging}} framework. That is because at that time > {{SparkSubmit}} doesn't yet know which application will run, and logging is > initialized differently for certain special applications (notably, the > shells). > It would be better if either {{SparkSubmit}} did logging initialization > earlier based on the application to be run, or did it in a way that could be > overridden later when the app initializes. > Without this, there are currently a few parts of {{SparkSubmit}} that > duplicates code from other parts of Spark just to avoid logging. For example: > * > [downloadFiles|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L860] > replicates code from Utils.scala > * > [createTempDir|https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/DependencyUtils.scala#L54] > replicates code from Utils.scala and installs its own shutdown hook > * a few parts of the code could use {{SparkConf}} but can't right now because > of the logging issue. -- 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
