Bad ivy.xml files published to repository.cloudera.com

We have a proxy to repository.cloudera.com in our nexus.pentaho.com to resolve cloudera artifacts for building Pentaho software. It seems a number of ivy.xml files got published to your repo that contain nothing but html for 404(s) and error pages. I've had to specifically blacklist these from our proxy to you, as they kill our legacy Ivy builds. Your repo is at the bottom of our list, but the way Ivy works, it will search long and hard for an ivy.xml before giving up and using the pom.xml it found WAAAAY further up the chain. I'm pretty sure that most of these third party artifacts don't even publish ivy.xml files.

In particular, these were some of the offenders:
