-------------------------------------
Summary: Non-null check for bootstrapServers field is incorrect in
KafkaSink
Key: FLINK-27174
URL: https://issues.apache.org/jira/browse/FLINK-27174
Project: Flink
Issue Type: Bug
Components: Connectors / Kafka
Affects Versions: 1.14.4
Reporter: Zhengqi Zhang

If the user-supplied kafkaProducerConfig contains bootstrapServers information,
there is no need to define the value of this field separately through the
setBootstrapServers method. Obviously, the current code doesn't notice this.

Perhaps we can check bootstrapServers as follows:

{color:#172b4d}Or check bootstrapServers like KafkaSourceBuilder.{color}
