Tom White commented on HADOOP-7035:
-----------------------------------

> I noticed it classifies a few changes as "incompatible" which I'd have 
> thought are compatible

It sometimes produces false positives (changes that are marked as incompatible, 
but in fact aren't), which is what these particular changes are. We might be 
able to improve the code to handle these cases.

> Would it be possible to also distinguish between "source-compatible" and 
> "binary-compatible" somehow?

This tool is for detecting source incompatible changes. For testing 
binary-compatibility we need another tool, like 
[Clirr|http://clirr.sourceforge.net/] (although I'm not sure how up to date 
this one is).
