root@dev:/usr/local/hello-samza# mvn clean package
root@dev:/usr/local/hello-samza# mkdir -p deploy/samza
root@dev:/usr/local/hello-samza# tar -xvf ./target/hello-samza-0.10.0-dist.tar.gz -C deploy/samza
执行Samza任务:
完成build Samza包之后，你就可以在grid使用t run-job.sh 脚本来完成一些任务了
root@dev:/usr/local/hello-samza # deploy/samza/bin/run-job.sh --config-factory=org.apache.samza.config.factories.PropertiesConfigFactory --config-path=file://$PWD/deploy/samza/config/wikipedia-feed.properties
上面的这个任务将会从Wikipedia上把实施反馈编辑撤销掉，会把这些编辑放到一个叫“thelinuxfaq-raw”的主题里面去.
让这个主题运行几分钟后，你再来看下Kafka 最后面的更新情况:
root@dev:/usr/local/hello-samza# deploy/kafka/bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic thelinuxfaq-raw
再次访问YARN UI界面(:8088). 你就看到Samza很正常的运行而不是有错误提示了!
关闭Samza:
一切都弄好了,你就可以使用grid脚本关闭所有的相关服务器了.
root@dev:/usr/local/hello-samza # bin/grid stop all
输出示例:
EXECUTING: stop all
EXECUTING: stop kafka
EXECUTING: stop yarn
stopping resourcemanager
stopping nodemanager
EXECUTING: stop zookeeper
JMX enabled by default
Using config: /usr/local/hello-samza/deploy/zookeeper/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
启动Samza :
同意的,你可以使用grid脚本来启动所有服务,
root@dev:/usr/local/hello-samza # bin/grid start all
输出示例:
EXECUTING: start all
EXECUTING: start zookeeper
JMX enabled by default
Using config: /usr/local/hello-samza/deploy/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
EXECUTING: start yarn
....
EXECUTING: start kafka
