Starting Storm via Ambari overrides certain parameters in storm.yaml . To reinstate the lost Ranger parameters so that the Storm plug-in can function, do the following:
In the Ambari console, go to the Storm Config tab.
Add a parameter value for nimbus.authorizer to com.xasecure.authorization.storm.authorizer.XaSecureStormAuthorizer.
Restart Storm via Ambari. The changes you just made are effective immediately, and the Ranger sto plug-in is enabled.
