Apache Hadoop ${project.version} is a point release in the 2.10.x release line,
building upon the previous stable release 2.10.1.
Here is a short overview of the major features and improvements.
* Common
* Authentication improvements when using an HTTP proxy server. This is
useful when accessing WebHDFS via a proxy server.
* A new Hadoop metrics sink that allows writing directly to Graphite.
* [Specification work](./hadoop-project-dist/hadoop-common/filesystem/index.html)
related to the Hadoop Compatible Filesystem (HCFS) effort.
* HDFS
* Support for POSIX-style filesystem extended attributes. See the
[user documentation](./hadoop-project-dist/hadoop-hdfs/ExtendedAttributes.html)
for more details.
* Using the OfflineImageViewer, clients can now browse an fsimage via
the WebHDFS API.
* The NFS gateway received a number of supportability improvements and
bug fixes. The Hadoop portmapper is no longer required to run the gateway,
and the gateway is now able to reject connections from unprivileged ports.
* The SecondaryNameNode, JournalNode, and DataNode web UIs have been
modernized with HTML5 and Javascript.
* YARN
* YARN's REST APIs now support write/modify operations. Users can submit and
kill applications through REST APIs.
* The timeline store in YARN, used for storing generic and
application-specific information for applications, supports authentication
through Kerberos.
* The Fair Scheduler supports dynamic hierarchical user queues, user queues
are created dynamically at runtime under any specified parent-queue.
