I’ve been out sick for a while, so couldn’t close this in time. Doing so now.

Hi all,

After a nearly month long [1] toil, with loads of help from Sangjin Lee and Akira Ajisaka,
and 153 (RC0)+7(RC1) commits later, I've created a release candidate RC1 for hadoop-2.6.1.

RC1 is RC0 [0] (for which I opened and closed a vote last week) + UI fixes for the issue Sangjin
raised (YARN-3171 and the dependencies YARN-3779, YARN-3248), additional fix to avoid incompatibility
(YARN-3740), other UI bugs (YARN-1884, YARN-3544) and the MiniYARNCluster issue (right patch
for YARN-2890) that Jeff Zhang raised.

The RC is available at: http://people.apache.org/~vinodkv/hadoop-2.6.1-RC1/

The RC tag in git is: release-2.6.1-RC1

The maven artifacts are available via repository.apache.org<http://repository.apache.org/>
at https://repository.apache.org/content/repositories/orgapachehadoop-1021

Some notes from our release process
 -  - Sangjin and I moved out a bunch of items pending from 2.6.1 [2] - non-committed but
desired patches. 2.6.1 is already big as is and is late by any standard, we can definitely
include them in the next release.
 - The 2.6.1 wiki page [3] captures some (but not all) of the context of the patches that
we pushed in.
 - Given the number of fixes pushed [4] in, we had to make a bunch of changes to our original
plan - we added a few improvements that helped us backport patches easier (or in many cases
made backports possible), and we dropped a few that didn't make sense (HDFS-7831, HDFS-7926,
HDFS-7676, HDFS-7611, HDFS-7843, HDFS-8850).
 - I ran all the unit tests which (surprisingly?) passed. (Except for one, which pointed out
a missing fix HDFS-7552).

As discussed before [5]
 - This release is the first point release after 2.6.0
 - I’d like to use this as a starting release for 2.6.2 in a few weeks and then follow up
with more of these.

Please try the release and vote; the vote will run for the usual 5 days.

[5] Planning Hadoop 2.6.1 release: http://markmail.org/thread/sbykjn5xgnksh6wg

 - Note that branch-2.6 which will be the base for 2.6.2 doesn't have these fixes yet. Once
2.6.1 goes through, I plan to rebase branch-2.6 based off 2.6.1.
 - The additional patches in RC1 that got into 2.6.1 all the way from 2.8 are NOT in 2.7.2
yet, this will be done as a followup.
