[ANNOUNCE] Apache Hadoop 3.0.0-beta1 has been released

[Andrew Wang <an...@cloudera.com>]

Hi all,

I'm pleased to announce the release of Apache Hadoop 3.0.0-beta1. This is
our first beta release in the 3.0.0 release line, and is planned to be the
last release before 3.0.0 GA. Beta releases are API stable but come with no
guarantee of quality, and are not intended for production use.

3.0.0-beta1 comprises 576 bug fixes, improvements, and other enhancements
since 3.0.0-alpha4. The full changelog [1] and release notes [2] are
available on the website, along with a higher-level description of major
changes in 3.0.0 [3].

Major features since alpha4 include the addition of S3Guard [4], which adds
strong consistency and performance improvements to the S3A filesystem
connector, and YARN Timeline Service v2 alpha2 [5], which further improves
on TSv2 alpha1 included in earlier 3.0.0 releases.

Since 3.0.0 GA is planned for next month, users are highly encouraged to
test this beta release. Let us know on the lists if we can help with your
testing efforts.

Thanks as always to the many contributors who helped with this release!

Cheers,
Andrew
