Siddharth Seth commented on HADOOP-9192:
----------------------------------------
+1 for the common changes. A minor issue with the MR change - which I'll
mention in the MR jira.
The YARN changes to make some fields "required" instead of "optional", and the
int64 to uint64 do make this an incompatible change w.r.t current branch-2 or
any of the previous alpha releases from this branch. Don't really see this as a
big issue though since I've always had the impression that the APIs are
currently unstable - and that they need to be looked at before compatibility
becomes a critical concern.
