Cmak: Will not attempt to authenticate using SASL (unknown error)

[zaqwsxa]

kafka's are in cluster between 2 servers on this server I have 3 instances kafka with different port
IOS: oracle linux 4.1.12-61.1.18.el7uek.x86_64

• kafka conf/server.properties
  added:
  host.name=x.x.x.x
  zookeeper.connect=x.x.x.x:6081,x.x.x.x:6081
  other things are basic configuraton

• kafka conf/zookeeper.properties
  changed data dir
  custer zookeeper
  server.3=x.x.x.x:6088:6089
  server.4=x.x.x.x:6088:6089

also I added a file with myid (each instances has diffrent number)

• kafka manager config
  only changed
  kafka-manager.zkhosts="x.x.x.x:6081"

How I'm running kafka manager
./bin/kafka-manager -Dconfig.file=conf/application.conf -Dkafka-manager.zkhosts="x.x.x.x:6081" -Dhttp.port=80

• important

• Other instances on port x.x.x.x:9081 in cluster are working propertly, everything is fine

• When I'm running other kafka manager on the same network subnet, why they are connecting each other?

So do I but with Zookeeper and Druid

[boisde]

So do I.

[sashati]

So do I in Druid for Zookeeper cluster

[mohithg]

Any updates here?

[msalihkarakasli]

So do I?

[xmzDesign]

So do I.

[melwynjensen]

So do I.

::Update:: Found the issue, it was an internal communication problem with Kafka to Zookeeper as it was not able to reach the node. Reassigned the nodes properly and it was up and running.

I set maxClientCnxns=1000 in ZooKeeper conf and it helps me

How did you re-assign the nodes?

[MagicJohnJang]

Finally work!
You got to create a cluster in Zookeeper first, then start Kafka!

Because you give Kafka multiple zookeeper addresses, which means you tell Kafka to connect to a cluster.
