Hi all,

voted to release Apache Hadoop 2.8.0.

Hadoop 2.8.0 is the first feature release since the year of 2015 in the
Hadoop-2.x
line, and brings a number of significant enhancements. I'd like to
highlight following major changes [1] coming in 2.8.0

   - HADOOP-12723, HADOOP-12548, HADOOP-12537 - S3A improvements
   - HADOOP-13037 - Azure Data Lake (ADL) support
   - HADOOP-12635 - WASB improvements

Hadoop HDFS

   - HDFS-9711, HDFS-8155, HDFS-9057 - WebHDFS enhancements
   - HDFS-9244 - Support nested encryption zones
   - HDFS-9239 - DataNode Lifeline Protocol

Hadoop YARN

   - YARN-41 - NM shutdown more graceful
   - YARN-313 - Full support for dynamic NM resource configuration
   - YARN-4349 - CallerContext support in YARN audit log

Hadoop MapReduce

   - MAPREDUCE-6304 - Allow node labels get specificed in submitting MR jobs
   - MAPREDUCE-6415 - Add a new tool to combine aggregated logs into HAR

This release has 2917 resolved issues with the following breakdown:

   - 774 in Hadoop Common
   - 1137 in HDFS
   - 774 in YARN
   - 232 in MapReduce

IMPORTANT NOTES
   - This release is *not* yet ready for production use. Issues are being
ironed
   out via testing and downstream adoption given numerous commits were
landing.
   Production users should wait for 2.8.1 release.

 Please see the Hadoop 2.8.0 Release Notes [3] for detailed list of issues
resolved.
The release news is posted on the Hadoop website too, you can go to the
downloads

Thanks to all those who contributed to the release!
