Subject [jira] [Commented] (SPARK-1403) Spark on Mesos does not set Thread's context class loader
Date Wed, 17 Jun 2015 12:59:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-1403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14589736#comment-14589736
] 

John Omernik commented on SPARK-1403:
-------------------------------------

This is occurring still in 1.4.0

I've attempted to look through the code to determine what may have changed but the Class Loading
code has shifted around quite a bit, and I could not pinpoint when the change, or which update
changed the code to break it again.  If there is anything I can do to help troubleshoot, please
advise.

> I can run spark 0.9.0 on mesos but not spark 1.0.0. This is because the spark executor
on mesos slave throws a  java.lang.ClassNotFoundException for org.apache.spark.serializer.JavaSerializer.
> The lengthy discussion is here: http://apache-spark-user-list.1001560.n3.nabble.com/java-lang-ClassNotFoundException-spark-on-mesos-td3510.html#a3513
