Just looked at it again, it was a quick hack to overcome a silly bug in ES
where False != false. Ambari does some tricks under the hood with bools where
they come out as True/False causing ES to fail. I can struggle with it some
more if it's important to you, but I think it's going to end with
> if False then value = "false" else value = "true"
somewhere in the code.
