Yes, there are a lot of changes since 0.5.5, of course, but we're not going to support an unreleased version on EMR. We did that for emr-4.1.0 (the first version to support Zeppelin), but it's much less confusing for us to support only released versions on EMR. As I mentioned earlier, we will upgrade to 0.5.6 once it's released, but as I also mentioned earlier, while the Notebook API appears fixed on 0.5.6, the Job API is not. The Job API, btw, is what allows you to run notebooks via the REST API. The Notebook API only lets you do CRUD on notebooks/paragraphs/crons.
FWIW, I also tried building Zeppelin from the tip of the master branch but still hit the same error when using the Job API, but that's not too surprising because v0.5.6 isn't too different from the tip of the master branch, particularly in the REST API code (other than the new Shiro Security API).
