Stavros Kontopoulos created SPARK-16379:
-------------------------------------------
Summary: Spark on mesos is broken due to race condition in Logging
Key: SPARK-16379
URL: https://issues.apache.org/jira/browse/SPARK-16379
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.0.0
Reporter: Stavros Kontopoulos
Priority: Blocker
This commit introduced a transient 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:

'/mesos/json.info_0000000152' in ZooKeeper

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