[ANNOUNCE] Apache Hadoop 3.0.0-alpha2 released

[Andrew Wang]

Hi all,

I'm pleased to announce the release of the second alpha in the 3.0.0
release line, 3.0.0-alpha2. This release contains 857 fixes, improvements,
and new features based on user feedback on the previous 3.0.0-alpha1
release. You can read the release notes [1] and changelog [2] for full
details.

Note that this is an alpha release, and comes with no guarantees as to
quality or compatibility, and is not intended for production use.

I'd like to highlight the following major changes [3] coming in alpha2
since alpha1:

* Shaded client jars added by HADOOP-11804, provided by the
"hadoop-client-api" and "hadoop-client-runtime" artifacts.
* New filesystem connectors for Microsoft Azure Data Lake and Aliyun Object
Storage System
* Support for opportunistic container scheduling and distributed scheduling
* Additional improvements to major Hadoop 3 features like Timeline Server
v2 and HDFS erasure coding

Please try out the release and let us know what you think. We're currently
planning one more alpha release before freezing for beta, so this is a key
time to incorporate feedback.

Best,
Andrew
