             Summary: Nimbus impersonation authorizer in defaults.yaml causes 
issues in secure mode
                 Key: STORM-1851
                 URL: https://issues.apache.org/jira/browse/STORM-1851
             Project: Apache Storm
          Issue Type: Bug
            Reporter: Arun Mahadevan
            Assignee: Arun Mahadevan
            Priority: Minor


  "nimbus.impersonation.authorizer" is set to "ImpersonationAuthorizer" by 
default and this causes issues when a user tries to submit topology as a 
different user in secure mode since the "nimbus.impersonation.acl" 
configuration is not set by default. Users need to set nimbus.impersonation.acl 
first before they can submit topology as a user other than "storm" in secure 
mode.

Removing this config allows users to submit topologies as any user in secure 
mode by default. Users can set up impersonation by providing both authorizer 
and the acls in storm.yaml.
