Hey @tzulitai, The 4.2.0 version does not bring any other dependencies, we
can safely upgrade.

## Check RabbitMQ Sink & Source
### Start a RabbitMQ(3.6.12)server on docker.
```
docker run -d --name rabbitmq --publish 5671:5671 \
--publish 5672:5672 --publish 4369:4369 --publish 25672:25672 --publish
15671:15671 --publish 15672:15672 \
rabbitmq:management
```
### WriteRabbitMQ job
```
final RMQConnectionConfig connectionConfig = new
RMQConnectionConfig.Builder()
.setHost("localhost")
.setPort(5672)
.setVirtualHost("flink")
.setPassword("guest")
.setUserName("guest")
.build();
DataStream<String> tsSource = env.addSource(
new SimpleStringGenerator(500));
tsSource.addSink(new RMQSink<String>(
connectionConfig, // config for the RabbitMQ
connection
"flink", // name of the RabbitMQ queue to
send messages to
new SimpleStringSchema()));
```
### ReadRabbitMQ job
```
final RMQConnectionConfig connectionConfig = new
RMQConnectionConfig.Builder()
.setHost("localhost")
.setPort(5672)
.setVirtualHost("flink")
.setPassword("guest")
.setUserName("guest")
.build();
DataStream<String> tsSource = env.addSource(new
RMQSource<String>(connectionConfig, "flink", // name of the
RabbitMQ queue to send messages to
false, new SimpleStringSchema()));
tsSource.addSink(new PrintSinkFunction<String>());
```
I observed rabbitmq admin UI and flink UI, the message was normally
received and sent, no exception log.
