Subject Re: [VOTE] Release Apache Hadoop 2.1.0-beta
Date Wed, 17 Jul 2013 19:24:30 GMT

Looks like this RC has gone stale and lots of bug fixes went into 2.1 and 2.1.0 branches and
there are 4-5 outstanding blockers. And from what I see in CHANGES.txt files there seems to
be a confusion about which branch to get in what.

I'm blowing off the current 2.1.0 release branch so that we can create a fresh release branch
and call voting on that. I'll fix CHANGES.txt entries as well as JIRA fix version for bugs
committed recently if there are inconsistencies.

Let me know if something is amiss while I do this.

the apis. They can implemented in a backward compat fashion if committed after 2.1.0. However,
this will require adding of differently-named apis ( different urls in case of the webservices
) and make the current version of the api deprecated and/or obsolete. YARN-818 which is currently
patch available also changes behavior.

does it make sense to try and pull them in and roll out a new RC after they are ready? Perhaps
Vinod can chime in if he is aware of any other such jiras under YARN-386 which should be considered
compat-related blockers for a 2.1.0 RC.
