Hello Alex,
ZooKeeper nodes that Kafka brokers create in /brokers/ids path, upon
registering themselves that they are available, are ephemeral, so not
persistent. Ephemeral ZooKeeper nodes live as long as ZooKeeper session
that created them is active. The /broker/ids child nodes are gone by
Quick update: digging into Zookeeper data, we observed that the /brokers/ids
path was empty. Restarting the kafka nodes repopulated zookeeper data, and now
the error is gone (we are able to create new topics).
We didn’t alter data in Zookeeper manually, but recently we added 2 nodes to a
3
Hello,
We recently migrated from Kafka 0.8 to 0.10, while keeping the log format and
internal communication at 0.9 version[1]. We have a cluster of two nodes which

Trying to create a new topic raises:
