good, glad we are back on track again.
BTW, we have already started build (IBM and OpenJDK SDK), unit test, and
limited integration testing  on x86 and POWER, results are promising.

Subject: [VOTE] - Release 2.0.5-beta

Folks,

A considerable number of people have expressed confusion regarding the
recent vote on 2.0.5, beta status etc. given lack of specifics, the voting
itself (validity of the vote itself, whose votes are binding) etc.

IMHO technical arguments (incompatibility b/w 2.0 & 2.1, current stability
of 3 features under debate etc.) have been lost in the discussion in favor
of non-technical (almost dramatic) nuances such as "seizing the moment".
There is now dangerous talk of tolerating incompatibility b/w 2.0 and 2.1)
- this is a red flag for me; particularly when there are just 3 features
being debated and active committers and contributors are confident of and
ready to stand by their work. All patches, I believe, are ready to be
merged in the the next few days per discussions on jira. This will,
clearly, not delay the other API work which everyone agrees is crucial. As
a result, I feel no recourse but to restart a new vote - all attempts at
calm, reasoned, civil discussion based on technical arguments have come to
naught - I apologize for the thrash caused to everyone's attention.

To get past all of this confusion, I'd like to present an alternate,
specific proposal for consideration.

I propose we continue the original plan and make a 2.0.5-beta release by
May end with the following content:
# HDFS-347
# HDFS Snapshots
# Windows support
# Necessary & final API/protocol changes such as:
 * Final YARN API changes: YARN-386
 * MR Binary Compatibility: MAPREDUCE-5108
 * Final RPC cleanup: HADOOP-8990

People working on the above features have all expressed considerable
comfort with them and are ready to stand-by to help expedite any necessary
bug-fixes etc. to get to stabilization quickly. I'm confident we can get
this release out by end of May. This sets stage for a hadoop-2.x GA release
right after with some more testing - this means I think I can quickly turn
around and make bug-fix releases as necessary right after 2.0.5-beta.

I request that people consider helping out with this plan and sign up to
help push hadoop-2.x to stability as outlined above. I believe this will
help achieve our shared goals of quickly stabilizing hadoop-2 and help
ensure we can support it for forseeable future in a compatible manner for
the benefit of our users and downstream projects.

Please vote, the vote will run the normal 7 days. Obviously, I'm +1.

thanks,
Arun
