I think we still need to incorporate the patches currently checked into branch 0.20. For example, Owen identified a major bug (BooleanWritable's comparator is broken) and filed a jira (HADOOP-6928) to put it in branch-0.20, where I reviewed it and checked it in, so this bug would be fixed in the next stable release. However this change is not in branch-0.20-security-203. Unless we put the delta from branch-0.20 into this release, it is missing important bug fixes that will cause it to regress against 20.3 (if it ever is released).
I am also nervous about changes like the one identified by HADOOP-7255. It looks like this change caused a significant regression in TestDFSIO throughput. It changes the core Task class, the commit log is a single line, and as far as I can tell it was not discussed or reviewed by anyone in the community. Don't changes like this at least deserve a jira before we release them?
