+** Authentication using delegation tokens
+
+  This feature is in the alpha mode and may change in the future.
+
+  You can use delegation tokens to authenticate yourself when using YARN RM webservices. However, this requires setting the right configurations. The conditions for this are:
+
+    * Hadoop is setup in secure mode with the authentication type set to kerberos.
+
+    * Hadoop HTTP authentication is setup with the authentication type set to kerberos
+
+  Once setup, delegation tokens can be fetched using the web services listed above and used as shown in an example below:
+

+  PUT http://<rm http address:port>/ws/v1/cluster/apps/application_1399397633663_0003/state
