Jungtaek Lim commented on SPARK-11818:
--------------------------------------
Removed "REPL" from title since it could confuse us to ExecutorClassLoader is a
REPL classloader.
It is a classloader for "executor" which is only used for REPL environment.
> ExecutorClassLoader cannot see any resources from parent class loader

> Key: SPARK-11818
> URL: https://issues.apache.org/jira/browse/SPARK-11818
> Project: Spark
> Issue Type: Bug
> Components: Spark Shell
> Affects Versions: 1.4.1
> Environment: CentOS 6, spark 1.4.1-hadoop2.4, mesos 0.22.1
> Reporter: Jungtaek Lim
>
> This issue starts from finding root reason from strange problem from
> spark-shell (and zeppelin) which is not a problem for spark-submit.

> After some hours (over days) digging into the detail, I found that
> ExecutorClassLoader cannot see any resource files which can be seen from
> parent class loader.
> ExecutorClassLoader itself doesn't need to lookup resource files cause REPL
> doesn't generate these, but it should delegate lookup to parent class loader.
> I'll provide the pull request which includes tests which fails on master soon.
