Gang, Thinking through the next couple of releases here, appreciate f/b.
# hadoop-2.2.1 I was looking through commit logs and there is a *lot* of content here (81 commits as on 11/7). Some are features/improvements and some are fixes - it's really hard to distinguish what is important and what isn't. I propose we start with a blank slate (i.e. blow away branch-2.2 and start fresh from a copy of branch-2.2.0) and then be very careful and meticulous about including only *blocker* fixes in branch-2.2. So, most of the content here comes via the next minor release (i.e. hadoop-2.3) In future, we continue to be *very* parsimonious about what gets into a patch release (major.minor.patch) - in general, these should be only *blocker* fixes or key operational issues. # hadoop-2.3 I'd like to propose the following features for YARN/MR to make it into hadoop-2.3 and punt the rest to hadoop-2.4 and beyond: * Application History Server - This is happening in a branch and is close; with it we can provide a reasonable experience for new frameworks being built on top of YARN. * Bug-fixes in RM Restart * Minimal support for long-running applications (e.g. security) via YARN-896 * RM Fail-over via ZKFC * Anything else? HDFS??? Overall, I feel like we have a decent chance of rolling hadoop-2.3 by the end of the year. Thoughts? thanks, Arun -- Arun C.
