Question

Hadoop 1.0.0 is released in dec 2011. And its in Beta version.

As per the below link security feature•Security (strong authentication via Kerberos authentication protocol) is added in hadoop 1.0.0 release.
http://www.infoq.com/news/2012/01/apache-hadoop-1.0.0

But we didnt find any documentation related to this in 1.0.0 documentation.

http://hadoop.apache.org/common/docs/r1.0.0/

Is there any documentation reg security feature available in 1.0.0 release and how to configure and use the same. Any inputs on this is greatly appreciated.

Hadoop Security documentation is some what sparse, Cloudera has the most exhaustive documentation for CDH3. It should be more or less applicable for Hadoop 1.0.0 also.

This link has consolidated information about articles/documentation about Hadoop Security.

BTW, Hadoop 1.0.0 is branding of 0.20.205 which had been in production for quite some time. There will also be Apache Hadoop 2.0.0 and 3.0.0 releases. Also, Hadoop 0.23 cut will also have the security features implemented and it also has the next generation MR architecture (MRv2).
