Kafka-eagle-2.0.3 Cannot obtain kafka cluster information
Kafka turns on JMX so that kafka cluster status can be viewed through Kafka-Eagle.
Solution 1:
Modify the kafka-run-class.sh script by adding JMX_PORT=9988 to the first line.

vim /moudle/kafka-2.6/bin/kafka-run-class.sh
JMX_PORT=9988

Solution 2:
start kafka JMX_PORT=9988

JMX_PORT=9988 kafka-server-start.sh -daemon /moudle/kafka-2.6/config/server.properties
