Is this setting in core-site.xml on all nodes in your cluster?
I’m attempting a HDP 1.3 install on a small centOS 6.4 cluster. I’ve taking the manual repo path and am stuck starting up datanodes. My namenode is up, but when I attempt to start a datanode it fails, and in the log directory there’s a jsvc.err file with the following text:
Initializing secure datanode resources
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
Caused by: java.lang.RuntimeException: Cannot start secure datanode in unsecure cluster

16/06/2013 12:17:04 18849 jsvc.exec error: Service exit with a return value of 3
I can see from the code:
that it appears to be doing kerebos authentication – which I don’t have a server setup for – but as far as I can tell this should be disabled.
in core-site.xml I have
Set the authentication for the cluster. Valid values are: simple or kerberos.
Which appears to be what sets the HADOOP_SECURITY_AUTHENTICATION value. So I’m not sure why it’s still trying to start in secure mode.
