6.5. Storm

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:

  1. In the Ambari console, go to the Storm Config tab.

  2. Add a parameter value for nimbus.authorizer to com.xasecure.authorization.storm.authorizer.XaSecureStormAuthorizer.

  3. Restart Storm via Ambari. The changes you just made are effective immediately, and the Ranger sto plug-in is enabled.
