That error probably means the overlord didn't start up. Its logs might have something interesting in them.

Everything is working fine.

But this is error i am getting and because of this issue indexing is not working and even overlord console also not working. i think this is probably missing some configuration from zookeeper.

/druid/discovery/druid:overlord/ does not have anything.

[Gian Merlino]

Have you customized any of the druid.service configs? If not, they should be ok out of the box. If the overlord console is not working, and you are getting this error, then both of those seem to indicate the overlord has some issue. I would double check its logs to make sure it's ok. Or its status endpoint at http://OVERLORD:8090/status.

this is output .

i did some changes in zookeeper /druid/discovery/druid:overlord/ 

here i have run following command.

 create /druid/discovery/druid:overlord/7175888f-4a66-4752-914b-ba4dd30eb0e4 {"name":"druid:overlord","id":"7175888f-4a66-4752-914b-ba4dd30eb0e4","address":"host","port":8090,"sslPort":null,"payload":null,"registrationTimeUTC":1538459763281,"serviceType":"DYNAMIC","uriSpec":null}

after that i am getting following error in router log
