             Summary: Add support for SNI names in SSL request
                 Key: KAFKA-9684
                 URL: https://issues.apache.org/jira/browse/KAFKA-9684
             Project: Kafka
          Issue Type: Improvement
            Reporter: Badai Aqrandista


When running Kafka cluster with SSL security behind HA Proxy, we need the 
client to send SSL packets with SNI name extension [1]. This will allow HA 
Proxy to forward the request to the relevant broker behind it (passthrough).

Java 7 and higher supports this by adding SNIHostName [2] to SSLParameters [3].
