使用kafka处理器api（不是dsl）从源主题读取并写入目标主题，对于单个kafka群集设置（即，如果源主题和目标主题都位于同一个群集上）来说效果很好，但是当源主题和目标主题位于不同的kafka群集上时，我得到的是目标处理器上下文的nullpointerexception

Topology
topology.addSource("mySource", "SourceTopic");
topology.addProcessor("SourceStreamProcessor",()->new SourceStreamProcessor(), "mySource");         

topology.addProcessor("TargetProcessor",()->new TargetProcessor(), "Target");
topology.addSink("sink1","OUTPUT_TOPIC1","TargetProcessor");
topology.addSink("sink2","OUTPUT_TOPIC2","TargetProcessor");

Properties sourceProcessorProps = new Properties();
props.put(StreamsConfig.APPLICATION_ID_CONFIG, "SourceStreamProcessor"); // Kafka Cluster 1
props.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "dev_Cluser_xx.org:9092");

Properties targetProcessorProps = new Properties();
props.put(StreamsConfig.APPLICATION_ID_CONFIG, "targetStreamProcessor"); // Kafka Cluster 2
props.put(StreamsConfig.BOOTSTRAP_SERVERS_CONFIG, "test_Cluser_xx.org:9092");

如何使用kafka streams处理器api将一个集群中的一个主题写入另一个集群中的另一个主题？
