Hi, I am running 1 node kafka setup in my local Docker and trying to create ACLs by using AdminClient API but receiving the following error:
[2018-11-12 23:21:20,065] TRACE [AdminClient clientId=adminclient-1] Metadata is not ready: we have not fetched metadata from the bootstrap nodes yet.

I am using Kafka 2.0 I could not find anything else, can you please help ? This might be related to single node setup ? Thanks in advance
