Modify custom service parameter in descriptor

How to edit a custom service parameter in a Knox descriptor using Cloudera Manager.

In this sample, we are going to update a previously entered service parameter - myCustomServiceParameter=myValue to myNewValue- for ATLAS in cdp-proxy. We change that entry, save our changes, and refresh our cluster.
  1. From Cloudera Manager > Knox > Configuration, change the service parameter in the Knox Simplified Topology Management - cdp-proxy panel.
    Change ATLAS:myCustomServiceParameter=myValue to Atlas:myCustomServiceParameter=myNewValue
  2. Save your changes.
  3. The ‘Refresh needed’ stale configuration indicator appears; click it and wait until the refresh process completes.
  4. Validate that custom service parameter got updated with the changes by navigating to the following URL: https://$KNOX_GATEWAY_HOST:$PORT/$GATEWAY_PATH/admin/api/v1/topologies/cdp-proxy.
