2017-07-25 Thread Raghu Angadi

Umesh, Thanks for the KIP. Straightforward and I think it's a good change. Unfortunately it is hard to tell how many people it would affect since we can't tell how many people have adjusted that config, but I think this is the right thing to do long term. A couple of quick things that might be

The reason I was looking for the CLI was to inspect into the service and get information like the host, port etc. But later I found I can get the same using the task command of dcos .. $ dcos marathon task list --json /schema-registry So, it's ok .. I don't need the specific CLI .. regards. On

The Confluent Schema Registry is a RESTful service, so no CLI really. What's your use case? If you are not familiar with it, the quickstart docs is a good place to start: http://docs.confluent.io/current/schema-registry/docs/intro.html#quickstart On Tue, Jul 25, 2017 at 2:09 AM, Debasish Ghosh
