-----------------------------------------------------------------
I'm also seeing problems when I'm trying to XInclude resources from different
JARs, specifically hadoop-common-test referencing anything in hadoop common JAR.
I don't actually know if this is a regression or not because it's something
I've never tested before
{code}
<configuration>
<include xmlns="http://www.w3.org/2001/XInclude";
href="/core-default.xml">
</include>
...

Here's the stack trace with the 001 patch applied. Its extra diagnostics are
valuable

> new Configuration().get() fails if core-site.xml isn't on the classpath
> -----------------------------------------------------------------------
>
> Key: HADOOP-14387
> URL: https://issues.apache.org/jira/browse/HADOOP-14387
> Project: Hadoop Common
> Issue Type: Bug
> Components: conf
> Affects Versions: 3.0.0-alpha3
> Environment: test run in downstream project with no core-site in
> test/resources
> Reporter: Steve Loughran
> Assignee: Jonathan Eagles
> Priority: Blocker
> Attachments: HADOOP-14387.1.patch
>
>
> If you try to create a config via {{new Configuration()}} and there isn't a
> {{core-site.xml}} on the CP, you get a stack trace. Previously it'd just skip
> the failure to load.
> This is a regression which breaks downstream apps that don't need a core-site
> to run, but do want to load core-default &c
