Question

我正在尝试使用从kafka源到hdfs的flume来提取数据。下面是我的flume conf文件。

flume1.sources = kafka-source-1
flume1.channels = hdfs-channel-1
flume1.sinks = hdfs-sink-1
flume1.sources.kafka-source-1.type = org.apache.flume.source.kafka.KafkaSource
flume1.sources.kafka-source-1.bootstrap.servers = localhost:9092
flume1.sources.kafka-source-1.zookeeperConnect = localhost:2181
flume1.sources.kafka-source-1.topic = MYNEWSFEEDS
flume1.sources.kafka-source-1.batchSize = 100
flume1.sources.kafka-source-1.channels = hdfs-channel-1
flume1.channels.hdfs-channel-1.type   = memory
flume1.sinks.hdfs-sink-1.channel = hdfs-channel-1
flume1.sinks.hdfs-sink-1.type = hdfs
flume1.sinks.hdfs-sink-1.hdfs.writeFormat = Text
flume1.sinks.hdfs-sink-1.hdfs.fileType = DataStream
flume1.sinks.hdfs-sink-1.hdfs.filePrefix = test-events
flume1.sinks.hdfs-sink-1.hdfs.useLocalTimeStamp = true
flume1.sinks.hdfs-sink-1.hdfs.path = hdfs://quickstart.cloudera:8020/tmp
flume1.sinks.hdfs-sink-1.hdfs.rollCount=100
flume1.sinks.hdfs-sink-1.hdfs.rollSize=0
flume1.channels.hdfs-channel-1.capacity = 10000
flume1.channels.hdfs-channel-1.transactionCapacity = 1000

我使用以下命令运行水槽代理：

sudo flume-ng agent --name flume1 --conf-file '/etc/flume-ng/conf/flafka.conf' Dflume.root.logger=TRACE,console

但我收到以下错误：

18/03/12 16:49:18 ERROR node.AbstractConfigurationProvider：Source 由于配置期间出错，kafka-source-1已被删除 org.apache.flume.conf.ConfigurationException：Bootstrap服务器必须在...指定 org.apache.flume.source.kafka.KafkaSource.doConfigure（KafkaSource.java:330）在 org.apache.flume.source.BasicSourceSemantics.configure（BasicSourceSemantics.java:65）在 org.apache.flume.source.AbstractPollableSource.configure（AbstractPollableSource.java:63）在 org.apache.flume.conf.Configurables.configure（Configurables.java:41）在 org.apache.flume.node.AbstractConfigurationProvider.loadSources（AbstractConfigurationProvider.java:326）在 org.apache.flume.node.AbstractConfigurationProvider.getConfiguration（AbstractConfigurationProvider.java:97）在 org.apache.flume.node.PollingPropertiesFileConfigurationProvider $ FileWatcherRunnable.run（PollingPropertiesFileConfigurationProvider.java:140）在 java.util.concurrent.Executors $ RunnableAdapter.call（Executors.java:471） at java.util.concurrent.FutureTask.runAndReset（FutureTask.java:304）在 java.util.concurrent.ScheduledThreadPoolExecutor中的$ ScheduledFutureTask.access $ 301（ScheduledThreadPoolExecutor.java:178）在 java.util.concurrent.ScheduledThreadPoolExecutor中的$ ScheduledFutureTask.run（ScheduledThreadPoolExecutor.java:293）在 java.util.concurrent.ThreadPoolExecutor.runWorker（ThreadPoolExecutor.java:1145）在 java.util.concurrent.ThreadPoolExecutor中的$ Worker.run（ThreadPoolExecutor.java:615）在java.lang.Thread.run（Thread.java:745）

虽然，我已经在conf文件中指定了Bootstrap服务器，但它仍然给出了同样的错误。尝试了许多排列组合但没有成功。

根据official JavaDoc，您应该替换

flume1.sources.kafka-source-1.bootstrap.servers = localhost:9092

与

flume1.sources.kafka-source-1.kafka.bootstrap.servers = localhost:9092

使用Flume将数据从kafka提取到HDFS :: ConfigurationException：必须指定Bootstrap Server
