Flume与KafKa集成

---

使用Flume把数据送到Kafka

• Source - local file
• Channel - local file
• Sink - Kafka

# test Agent
test.sources = testSource
test.channels = testChannel
test.sinks = testSink

test.sources.testSource.type = spooldir
test.sources.testSource.deserializer = LINE
test.sources.testSource.deserializer.maxLineLength = 6400
test.sources.testSource.spoolDir = /events/input/intra/test
test.sources.testSource.includePattern = test_[0-9]{4]-[0-9]{2]-[0-9]{2].csv
test.sources.testSource.channels = testChannel

test.channels.testChannel.type = file
test.channels.testChannel.checkpointDir = /var/flume/checkpoint/test
test.channels.testChannel.dataDirs = /var/flume/data/test

test.sinks.testSink.type = oorg.apache.flume.sink.kafka.KafkaSink
test.sinks.testSink.batchSize = 640
test.sinks.testSink.brokerList = localhost:6667
test.sinks.testSink.topic = test1
test.sinks.testSink.channel = testChannel

使用Flume把Kafka中的数据送到HDFS

• Source - Kafka
• Channel - Memory
• Sink - HDFS

# Sources, channels, and sinks are defined
kgc.sources = kafkaSource
kgc.channels = memoryChannel
kgc.sinks = hdfsSink

# kafka Source
kgc.sources.kafkaSource.type = org.apache.flume.source.kafka.KafkaSource
kgc.sources.kafkaSource.zookeeperConnect = localhost:2181
kgc.sources.kafkaSource.topic = demo
kgc.sources.kafkaSource.batchSize = 1
kgc.sources.kafkaSource.channels = memoryChannel

# memory Channel
kgc.channels.memoryChannel.type = memory
kgc.channels.memoryChannel.capacity = 10000
kgc.channels.memoryChannel.transactioncapacity = 1000

# hdfs Sink
kgc.sinks.hdfsSink.channel = memoryChannel
kgc.sinks.hdfsSink.type = hdfs
kgc.sinks.hdfsSink.hdfs.writeFormat = Text
kgc.sinks.hdfsSink.hdfs.fileType = DataStream
kgc.sinks.hdfsSink.hdfs.filePrefix = kgcEvents
kgc.sinks.hdfsSink.hdfs.useLocalTimeStamp = true
kgc.sinks.hdfsSink.hdfs.path = /tmp/demo/%y-%m-%d
kgc.sinks.hdfsSink.hdfs.rollCount=1
kgc.sinks.hdfsSink.hdfs.rollSize=0

Kafka作为Channel把数据送到HDFS

• source - local file
• channel - Kafka
• Sink - HDFS

exercise.sources = execSource
exercise.channels = kafkaChannel
exercise.sinks = hdfsSink
 
exercise.sources.execSource.type = exec
exercise.sources.execSource.command = /usr/bin/vmstat 1
exercise.sources.execSource.channels = kafkaChannel
 
exercise.channels.kafkaChannel.type = org.apache.flume.channel.kafka.KafkaChannel
exercise.channels.kafkaChannel.capacity = 10000
exercise.channels.kafkaChannel.transactionCapacity = 1000
exercise.channels.kafkaChannel.brokerList = localhost:6667
exercise.channels.kafkaChannel.topic = flafka
exercise.channels.kafkaChannel.zookeeperConnect = localhost:2181
exercise.channels.kafkaChannel.parseAsFlumeEvent = true
 
exercise.sinks.hdfsSink.type = hdfs
exercise.sinks.hdfsSink.hdfs.path = /tmp/kafka/channel
exercise.sinks.hdfsSink.hdfs.rollInterval = 5
exercise.sinks.hdfsSink.hdfs.rollSize = 0
exercise.sinks.hdfsSink.hdfs.rollCount = 0
exercise.sinks.hdfsSink.hdfs.fileType = DataStream
exercise.sinks.hdfsSink.channel = kafkaChannel
