Flume配置文件:

simple-agent.sources = netcat-source
simple-agent.sinks = spark-sink
simple-agent.channels = memory-channel

#Describe/configure the source
simple-agent.sources.netcat-source.type = netcat
simple-agent.sources.netcat-source.bind = centos
simple-agent.sources.netcat-source.port= 44444

# Describe the sink
simple-agent.sinks.spark-sink.type=org.apache.spark.streaming.flume.sink.SparkSink
simple-agent.sinks.spark-sink.hostname= centos 
simple-agent.sinks.spark-sink.port= 41414

simple-agent.channels.memory-channel.type = memory
simple-agent.channels.memory-channel.capacity = 1000
simple-agent.channels.memory-channel.transactionCapacity = 100

simple-agent.sources.netcat-source.channels = memory-channel
simple-agent.sinks.spark-sink.channel = memory-channel

但是在启动Flume时,报以下错误:

2019-10-16 11:35:14,559 (conf-file-poller-0) [ERROR - org.apache.flume.node.PollingPropertiesFileConfigurationProvider$FileWatcherRunnable.run(PollingPropertiesFileConfigurationProvider.java:142)] Failed to load configuration data. Exception follows.

解决方案:

由于用到了agent的sink是 org.apache.spark.streaming.flume.sink.SparkSink类型,需要把spark-streaming-flume-sink_2.11-2.4.3.jar复制到flume的lib目录,否则,会报找不到org.apache.spark.streaming.flume.sink.SparkSink类的错误。
