precedence over Spark jars does not work as expected
[ https://issues.apache.org/jira/browse/SPARK-1863?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hyukjin Kwon resolved SPARK-1863.
---------------------------------
Resolution: Incomplete
> Allowing user jars to take precedence over Spark jars does not work as expected
> -------------------------------------------------------------------------------
>
> Key: SPARK-1863
> URL: https://issues.apache.org/jira/browse/SPARK-1863
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.0.0
> Reporter: koert kuipers
> Priority: Minor
> Labels: bulk-closed

> See here:
> http://apache-spark-user-list.1001560.n3.nabble.com/java-serialization-errors-with-spark-files-userClassPathFirst-true-td5832.html
> The issue seems to be that within ChildExecutorURLClassLoader userClassLoader has no visibility on classes managed by parentClassLoader because their is no parent/child relationship. What this means that if a class is loaded by userClassLoader and it refers to a class loaded by parentClassLoader you get a NoClassDefFoundError.
