--------------------------------------
Summary: Surprising behaviour when bootstrap servers are separated
by semicolons
Key: KAFKA-10713
URL: https://issues.apache.org/jira/browse/KAFKA-10713
Project: Kafka
Issue Type: Improvement
Reporter: Mickael Maison
When creating a Kafka client with bootstrap.servers set to
"kafka-0:9092;kafka-1:9092;kafka-2:9092", it has a strange behaviour.
For once, there's no warning or error messages. The client will connect and
start working. However, it will only use the hostname after the last semicolon!
kafka-2 in this example!
assertEquals("kafka-2", getHost("kafka-1:1234;kafka-1:1234;kafka-2:1234"));
I believe semicolon are not valid characters in hostname/domain names, so we
should be able to provide better validation.
