解压安装包:将下载的安装包解压到指定目录,例如/home/samza。
配置环境变量:编辑~/.bashrc文件,添加以下内容:
export SAMZA_HOME=/home/samza
export PATH=$PATH:$SAMZA_HOME/bin
zookeeper.connect=localhost:2181
job.factory.class=org.apache.samza.job.yarn.YarnJobFactory
task.class=org.apache.samza.examples.wikipedia.task.WikipediaFeedStreamTask
systems.wikipediastream.samza.factory=org.apache.samza.system.kafka.KafkaSystemFactory
systems.wikipediastream.samza.msg.serde.class=org.apache.samza.serializers.JsonSerdeFactory
systems.wikipediastream.consumer.zookeeper.connect=localhost:2181
systems.wikipediastream.consumer.bootstrap.servers=localhost:9092
systems.wikipediastream.consumer.zookeeper.broker.servers=localhost
systems.wikipediastream.consumer.kafka.consumer.id=wikipedia-feed
task.inputs=wikipediastream
task.checkpoint.factory=org.apache.samza.checkpoint.kafka.KafkaCheckpointManagerFactory
task.checkpoint.system=kafka
task.checkpoint.replication.factor=1
./run-job.sh --config-factory=org.apache.samza.config.factories.PropertiesConfigFactory --config-path=file://$SAMZA_HOME/conf/job.properties
以上就是安装和配置Samza的基本步骤。根据实际需求可以进一步配置和优化Samza任务。
