我有 2 台服务器。在服务器 A 上附加了一个日志文件。服务器 B 具有 HBase。所以我将 Flume NG 安装到服务器 A 并使用 tail exec 作为源和 avro 接收器，并将服务器 B avro 作为源和 hbase 作为接收器。在服务器 A 上运行代理时，出现以下异常：

服务器 A 上的水槽 conf 是：
agent1.sinks.avroSink.channel = memoryChannel
agent1.sinks.avroSink.type = avro
agent1.sinks.avroSink.hostname = sun
agent1.sinks.avroSink.port = 41414
服务器 B 上的水槽配置：
agent1.sources.avroSource.type = avro
agent1.sources.avroSource.channels = memoryChannel
agent1.sources.avroSource.bind = 10.xx.yy.zz
agent1.sources.avroSource.port = 41414
