스마트카 상태정보(SmartCarStatusInfo_20160101.txt)를 car-batch-log/ 로 복사해서 Flume이 Hadoop에 저장하는 처리중 에러가 발생합니다. 어디를 잘못 했을까요? 에러 내용 -------------------------------------------------------------------------------------- 2021-05-04 08:51:25,195 INFO org.apache.flume.node.AbstractConfigurationProvider: Created channel DriverCarInfo_Channel 2021-05-04 08:51:25,195 INFO org.apache.flume.channel.DefaultChannelFactory: Creating instance of channel SmartCarInfo_Channel type memory 2021-05-04 08:51:25,203 INFO org.apache.flume.node.AbstractConfigurationProvider: Created channel SmartCarInfo_Channel 2021-05-04 08:51:25,205 INFO org.apache.flume.source.DefaultSourceFactory: Creating instance of source SmartCarInfo_SpoolSource, type spooldir 2021-05-04 08:51:25,234 ERROR org.apache.flume.node.PollingPropertiesFileConfigurationProvider: Unhandled error java.lang.NoSuchMethodError: org.apache.flume.Context.getSubProperties(Ljava/lang/String;)Ljava/util/Map;         at org.apache.flume.source.SpoolDirectorySource.configure(SpoolDirectorySource.java:176)         at org.apache.flume.conf.Configurables.configure(Configurables.java:41)         at org.apache.flume.node.AbstractConfigurationProvider.loadSources(AbstractConfigurationProvider.java:325)         at org.apache.flume.node.AbstractConfigurationProvider.getConfiguration(AbstractConfigurationProvider.java:105)         at org.apache.flume.node.PollingPropertiesFileConfigurationProvider$FileWatcherRunnable.run(PollingPropertiesFileConfigurationProvider.java:145)         at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511)

안녕하세요 SmartCar_Agent를 정의할 때에는 SmartCar_Agent.xxx = xxx과 같이 정의를 했는데 DriverCarInfo를 정의할 때에는 한 칸 띄는 것만으로 정의를 하더라고요 그렇다면 추가적인 Agent를 작성하게 되면 DriverCarInfo_Agent를 정의한 것처럼 한 칸 띄고 해야하는 건가요?
