Sangjin Lee updated HADOOP-13398:
---------------------------------
Attachment: HADOOP-13398-HADOOP-13070.04.patch
v.4 patch posted.
This implements the support for ClassLoader.getResources() per proposal
mentioned above and on HADOOP-13070.
This is now a pretty much ready patch. The only thing I haven't done is to
merge the new unit test into {{TestApplicationClassLoader}} and reconcile them.
Again, your reviews and feedback would be greatly appreciated. Thanks!

>
> Today, a user class is able to trigger loading a class from Hadoop's
> dependencies, with or without the use of {{ApplicationClassLoader}}, and it
> creates an implicit dependence from users' code on Hadoop's dependencies, and
> as a result dependency conflicts.
> We should modify {{ApplicationClassLoader}} to prevent a user class from
> loading a class from the parent classpath.
> This should also cover resource loading (including
> {{ClassLoader.getResources()}} and as a corollary {{ServiceLoader}}).
