我已经像下面这样配置了我的水槽代理。不知何故，水槽代理无法正常运行。它一直挂着，没有任何错误。下面的配置有没有问题。
仅供参考：我有一个名为“country”的文件，其中包含硬编码标题作为状态
#Define sources, sink and channels
foo.sources = s1
foo.channels = chn-az chn-oth
foo.sinks = sink-az sink-oth
#
### # # Define a source on agent and connect to channel memory-channel.
foo.sources.s1.type = exec
foo.sources.s1.command = cat /home/hadoop/flume/country.txt
foo.sources.s1.batchSize = 1
foo.sources.s1.channels = chn-ca chn-oth
#selector configuration
foo.sources.s1.selector.type = multiplexing
foo.sources.s1.selector.header = state
foo.sources.s1.selector.mapping.AZ = chn-az
foo.sources.s1.selector.default = chn-oth
#
#
### Define a memory channel on agent called memory-channel.
foo.channels.chn-az.type = memory
foo.channels.chn-oth.type = memory
#
#
##Define sinks that outputs to hdfs.
foo.sinks.sink-az.channel = chn-az
foo.sinks.sink-az.type = hdfs
foo.sinks.sink-az.hdfs.path = hdfs://master:9099/user/hadoop/flume
foo.sinks.sink-az.hdfs.filePrefix = statefilter
foo.sinks.sink-az.hdfs.fileType = DataStream
foo.sinks.sink-az.hdfs.writeFormat = Text
foo.sinks.sink-az.batchSize = 1
foo.sinks.sink-az.rollInterval = 0
#
foo.sinks.sink-oth.channel = chn-oth
foo.sinks.sink-oth.type = hdfs
foo.sinks.sink-oth.hdfs.path = hdfs://master:9099/user/hadoop/flume
foo.sinks.sink-oth.hdfs.filePrefix = statefilter
foo.sinks.sink-oth.hdfs.fileType = DataStream
foo.sinks.sink-oth.batchSize = 1
foo.sinks.sink-oth.rollInterval = 0
谢谢，维诺特
