The release notes for 0.= 22 (http://hadoop.apache.org/common/releases= .html#10+December%2C+2011%3A+release+0.22.0+available) it says

>The following features are not supported in Hadoop 0.22.0.

= =A0=A0=A0 >Security.
=A0=A0=A0 >Latest optimizations of the MapRed= uce framework introduced in the Hadoop 0.20.security line of releases.
= =A0=A0=A0 >Disk-fail-in-place.
=A0=A0=A0 >JMX-based metrics v2.

By Security missing, what all fe= atures are missing? Does it mean Kerberos integration is missing?

In= o.a.h.hdfs.server.datanode.SecureDataNodeStarter.java, the following code = is there

=A0=A0=A0 if(!conf.get(HADOOP_SECURITY_AUTHENTICATION).equals("ker= beros"))
=A0=A0=A0=A0=A0 throw new RuntimeException("Cannot st= art secure datanode in unsecure cluster");
