Subject Can't see topics anymore after upgrade from 1.1 to 2.2.1
Date Mon, 03 Jun 2019 14:00:39 GMT

Just upgraded my Kafka test environment from 1.1 to 2.2.1.
What I did:
1) Untarred Scala 2.11-Kafka 2.2.1 file in /opt directory (BTW: OS = CentOS 7.6) which creates
directory kafka_2.11-2.2.1
2) Removed symbolic link "kafka" from old environment kafka_2.11-1.1.0
3) Created a new symbolic link "kafka" to the new directory kafka_2.11-2.2.1
4) Started zookeeper (no errors)
5) Added inter.broker.protocol.version=1.1 to server.config
6) Started kafka (no errors)
7) From the bin directory: ./kafka-topics.sh --bootstrap-server localhost:9092 --list

This produces an empty list (no output).

Stopping kafka and kafka-zookeeper, reverting the symbolic link to the old environment and
starting kafka-zookeeper and kafka again, followed by ./kafka-topics.sh --zookeeper localhost:2181
gives me all my topics again.

What am I doing wrong ?
