Marcelo Vanzin resolved SPARK-15652. ------------------------------------ Resolution: Fixed Assignee: Subroto Sanyal Fix Version/s: 2.0.0 > Missing org.apache.spark.launcher.SparkAppHandle.Listener notification if > SparkSubmit JVM shutsdown > --------------------------------------------------------------------------------------------------- > > Key: SPARK-15652 > URL: https://issues.apache.org/jira/browse/SPARK-15652 > Project: Spark > Issue Type: Bug > Affects Versions: 1.6.0 > Reporter: Subroto Sanyal > Assignee: Subroto Sanyal > Priority: Critical > Fix For: 2.0.0 > > Attachments: SPARK-15652-1.patch, spark-launcher-client-hang.jar > > > h6. Problem > In case SparkSubmit JVM goes down even before sending the job complete > notification; the _org.apache.spark.launcher.SparkAppHandle.Listener_ will > not receive any notification which may lead to the client using SparkLauncher > hang indefinitely. > h6. Root Cause > No proper exception handling at > org.apache.spark.launcher.LauncherConnection#run when an EOFException is > encountered while reading over Socket Stream. Mostly EOFException will be > thrown at the suggested > point(_org.apache.spark.launcher.LauncherConnection.run(LauncherConnection.java:58)_) > if the SparkSubmit JVM is shutdown. > Probably, it was assumed that SparkSubmit JVM can shut down only with normal > healthy completion but, there could be scenarios where this is not the case: > # OS kill the SparkSubmit process using OOM Killer. > # Exception while SparkSubmit submits the job, even before it starts > monitoring the application. This can happen if SparkLauncher is not > configured properly. There might be no exception handling in > org.apache.spark.deploy.yarn.Client#submitApplication(), which may lead to > any exception/throwable at this point lead to shutting down of JVM without > proper finalisation > h6. Possible Solutions > # In case of EOFException or any other exception notify the listeners that > job has failed > # Better exception handling on the SparkSubmit JVM side (though this may not > resolve the problem completely) -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
