WARN conf.FlumeConfiguration: Could not configure sink sink1 due to: No channel configured for sink: sink1 org.apache.flume.conf.ConfigurationException: No channel configured for sink: sink1

1、错误如下所示，启动flume采集文件到hdfs案例的时候，出现如下所示的错误：

大概是说No channel configured for sink，所以应该是sink哪里配置出现了错误，百度了一下，然后检查了一下自己的配置:

2、解决方法如下所示：

参考链接如https://stackoverflow.com/questions/31798967/flume-could-not-configure-sink-no-channel-configured-for-sink

作者说应该是下面那种配置，一下子就明白了，自己的配置错误了，自己的如下所示：

 

修改以后，继续启动，解决问题。
