@yogesh turkane

Seems like your coordinator process is not registered or some configuration issues, from logs I did observe below error

2018-10-04T06:43:50,101 ERROR [main] io.druid.curator.discovery.ServerDiscoverySelector - No server instance found for [druid/coordinator]
2018-10-04T06:43:50,101 WARN [main] - Failed on try 1, retrying in 886ms. No known server

Check the configurations and restart Druid services.
