----------------------------
Resolution: Not A Problem
> Failed to dynamically update kafka certificate in kafka 2.0.0
> -------------------------------------------------------------
>
> Key: KAFKA-7229
> URL: https://issues.apache.org/jira/browse/KAFKA-7229
> Project: Kafka
> Issue Type: Bug
> Components: security
> Affects Versions: 2.0.0
> Environment: Ubuntu 14.04.5 LTS
> Reporter: Yu Yang
> Priority: Critical
>
> In kafka 1.1, we use the following command in a cron job to dynamically
> update the certificate that kafka uses :
> kafka-configs.sh --bootstrap-server localhost:9093 --command-config
> /var/pinterest/kafka/client.properties --alter --add-config
> listener.name.ssl.ssl.keystore.location=/var/certs/kafka/kafka.keystore.jks.1533141082.38
> --entity-type brokers --entity-name 9
> In kafka 2.0.0, the command fails with the following exception:
> [2018-08-01 16:38:01,480] ERROR [AdminClient clientId=adminclient-1]
> Connection to node -1 failed authentication due to: SSL handshake failed
> (org.apache.kafka.clients.NetworkClient)
> Error while executing config command with args '--bootstrap-server
> localhost:9093 --command-config /var/pinterest/kafka/client.properties
> --alter --add-config
