Hi Team,

I am trying to modify Knox -> Configs->Advance Topology using below link but no luck.

https://cwiki.apache.org/confluence/display/AMBARI/Modify+configurations

      },

and executed below command -

 curl -H 'X-Requested-By:ambari' -u admin:admin -X PUT --data @test.json http://localhost:8080/api/v1/clusters/hdptest/

But no luck.

Can you please let me know how can i achieve this?
