启动Flume报错ERROR - org.apache.flume.lifecycle.LifecycleSupervisor$MonitorRunnable.run(LifecycleSupe

启动Flume报错：
[ERROR - org.apache.flume.lifecycle.LifecycleSupervisor$MonitorRunnable.run(LifecycleSupervisor.java:251)] Unable to start SinkRunner: { policy:org.apache.flume.sink.DefaultSinkProcessor@65bf32fc counterGroup:{ name:null counters:{} } } - Exception follows.
org.apache.kafka.common.KafkaException: Failed to construct kafka producer

我这个原因是kafka版本和flume版本不一致导致的 ，换了个flume1.9.0就没有报错了。
