I am getting error for knox and unable to access any service ui.

"2016-09-19 21:43:49,159 ERROR hadoop.gateway (GatewayServer.java:handleCreateDeployment(479)) - Failed to deploy topology nodemanagerui: org.apache.hadoop.gateway.deploy.DeploymentException: Failed to contribute provider. Role: iop-util Name: user-name. Please check the topology for errors in name and role and that the provider is on the classpath."

Nothings looks out of place to me, so far. Just not getting anything other than admin topology war in deployment folder. Please suggest something.

This could most likely be because of an error in your topology file. Did you create a new topology file ? also it would be helpful if you could post your topology snippet.
