Invalid or missing resources: hadoop-aarch64

[Michael Reed]

When attempting to use juju-resources charmhelpers appears to be missing.

I was not using the latest version of this charm, hadoop-aarch64 is the missing resource.

sudo juju-resources fetch --all -r resources.yaml -d /tmp/hadoop_resources_current/apache-hadoop-yarn-master/

We have hadoop-2.4.1.tgz for x86_64 and aarch64. When fetching --all resources from a resources.yaml, juju-resources gives an "invalid" error for aarch64 because the x86_64 tarball has the same base name.

juju-resources should handle the case when multiple resources have the same base filename.
