我有2台服务器。日志文件附加在服务器A上。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上运行代理程序时，我遇到以下异常：

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：
agent1.sources.avroSource.type = avro
agent1.sources.avroSource.channels = memoryChannel
agent1.sources.avroSource.bind = 10.xx.yy.zz
agent1.sources.avroSource.port = 41414
答案 0 :(得分：4)
必须有B主机名。 B必须有其第n个主机名。 请参阅以下链接： http://pic.dhe.ibm.com/infocenter/bigins/v2r1/index.jsp?topic=%2Fcom.ibm.swg.im.infosphere.biginsights.admin.doc%2Fdoc%2FUserScenarioFlume.html
