I updated the ticket with some more information.
If you still cannot reproduce it, feel free to ping me and I will give
you access to the instance.
At some point I was wondering if it is because I am mixing the amazon
ami with centos6 repos, but given every other service I try do work...

Sure. Any recommendations?

Thanks!
Will do!

I was not using puppet (on purpose).
I will give it another shot by looking at what our puppet recipes are
doing and see if any of these changes can be baked directly into our
packages.

No. Fully distributed

Actually, it was the elasticsearch sink for flume which had me update
Apache Lucene jars.

I will probably open a ticket against Apache Flume directly sometimes
this week to ask for some clarification.

I had the same reaction.
But this was reported as blocked by noscript.
Also it seems to be a configuration activated by default:

Sure.
Do you have anything particular in mind?
Not yet. But will do.
Thanks,
