Oh yea, I guess the standard Spark distributions are compiled with both
profiles. I created a separate `YARNHadoopFSCredentialProvider` to handle
YARN's specific functionality (renewer, extra filesystems, etc.), but I guess I
could do that through parameterization rather than a separate class, since it
seems we can't have a YARN specific class through service loading. How does
that sound?
