[FLINK-4439] Validate 'bootstrap.servers' config in flink kafka consuâ¦
Hello everybody,
I would like to contribute a small improvement to Flink.
Lately, I was using the FlinkKafkaConsumer08 to write a streaming topology
in flink. Somehow I mistakenly configured the 'boostrap.servers' for the kafka
config with invalid hosts.
The message that flink provided was not clearly stating what the problem
was. Hence, my improvement consists of a validation of the servers provided in
'boostrap.servers'.
If none of the configured servers are valid then we should fail-fast and a
validation exception should be thrown. If at lease one server is valid then we
don't throw any exception.
See for more info: https://issues.apache.org/jira/browse/FLINK-4439
