• Configuring Flume jobs

 

 

Flume transmitted using the data collected to Kafka TailDir Source and HDFS. Specific configuration is as follows:

Taildir-HdfsAndKafka-Agnet.sources = taildir-source   
Taildir-HdfsAndKafka-Agnet.channels = c1 c2
Taildir-HdfsAndKafka-Agnet.sinks = hdfs-sink kafka-sink

Taildir-HdfsAndKafka-Agnet.sources.taildir-source.type = TAILDIR
Taildir-HdfsAndKafka-Agnet.sources.taildir-source.filegroups = f1
Taildir-HdfsAndKafka-Agnet.sources.taildir-source.filegroups.f1 = /home/hadoop/data/flume/HdfsAndKafka/input/.*

Taildir-HdfsAndKafka-Agnet.channels.c1.type = memory
Taildir-HdfsAndKafka-Agnet.channels.c2.type = memory

Taildir-HdfsAndKafka-Agnet.sinks.hdfs-sink.type = hdfs
Taildir-HdfsAndKafka-Agnet.sinks.hdfs-sink.hdfs.path = hdfs://hadoop001:9000/flume/HdfsAndKafka/%Y%m%d%H%M

Taildir-HdfsAndKafka-Agnet.sinks.hdfs-sink.hdfs.rollSize = 100000000

Taildir-HdfsAndKafka-Agnet.sinks.hdfs-sink.hdfs.fileType=DataStream
Taildir-HdfsAndKafka-Agnet.sinks.hdfs-sink.hdfs.writeFormat=Text

Taildir-HdfsAndKafka-Agnet.sinks.kafka-sink.type = org.apache.flume.sink.kafka.KafkaSink
Taildir-HdfsAndKafka-Agnet.sinks.kafka-sink.brokerList = localhost:9092
Taildir-HdfsAndKafka-Agnet.sinks.kafka-sink.topic = wsk_test
