[jira] [Updated] (SPARK-16379) Spark on mesos is broken due to race condition in Logging

     [ https://issues.apache.org/jira/browse/SPARK-16379?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stavros Kontopoulos updated SPARK-16379:
----------------------------------------
    Description: 
This commit introduced a transient lazy log val: https://github.com/apache/spark/commit/044971eca0ff3c2ce62afa665dbd3072d52cbbec

This has caused problems in the past:
https://github.com/apache/spark/pull/1004

One commit before that everything works fine.

I spotted that when my CI started to fail:
https://ci.typesafe.com/job/mit-docker-test-ref/191/

You can easily verify it by installing mesos on your machine and try to connect with spark shell from bin dir:

./spark-shell --master mesos://zk://localhost:2181/mesos --conf spark.executor.url=$(pwd)/../spark-2.0.0-SNAPSHOT-bin-test.tgz

It gets stuck at the point where it tries to create the SparkContext.

Logging gets stuck here:

I verified it also by changing @transient lazy val log to def and it works as expected.
