Hi, there have been some changes to have consistent input fields for SNN, NN and DN dirs. This is coming in Ambari 1.7.0 https://issues.apache.org/jira/browse/AMBARI-6530 ...

Ambari 1.6 Bug>> Secondary NameNode data
In Ambari 1.6, for the property field “Secondary NameNode data”, Ambari does not seem to recognize a comma-delimited list of directories. Instead, it always accepts only one of the specified directories, and displays it.
I was using FireFox 29.0.1 on Mac OS X 10.8.5.
