Folks,

It gives me great pleasure to announce that the Apache Hadoop community has
voted to release Apache Hadoop 2.4.0.

hadoop-2.4.0 is the second release for the year 2014, and brings a number of
enhancements to the core platform, both HDFS & YARN: • Support for Access Control Lists in HDFS • Support for Rolling Upgrades of HDFS • Switch to protocol-buffers for HDFS FSImage for smooth operational upgrades • Complete HTTPS support in HDFS • Support for Automatic Failover of the YARN ResourceManager • Enhanced support for new applications on YARN with Application History Server
and Application Timeline Server • Support for strong SLAs in YARN CapacityScheduler via Preemption

Of course, a number of bug-fixes, enhancements etc. have also made it into
hadoop-2.4.0; there-by continuing to improve Apache Hadoop. Please see the
release notes for more details.

Thanks to all those who contributed to the release!

Arun
