Answer 1

actually there is no namespace called "osm" everything running on default namespace

Refer kubernetes documentation.

As the error says, there's no service kafka in an osm namespace (whether that exists, or not), that can be reached. Remove .osm from that address, or change it to .default, assuming that there really is a Service named kafka available at port 9092
