创建kafka日志主题（自行创建）

主题：elk_log_info

搭建ELK环境（自行搭建）

编辑logstash.conf文件

input {
  kafka {
    bootstrap_servers => ["host1:9092,host2:9092,host3:9092"]
    group_id => "elk-consumer"
    auto_offset_reset => "latest"
    consumer_threads => 3
    decorate_events => true
    topics => ["elk_log_info"]
    type => "zc"
    codec => "json"
    max_partition_fetch_bytes => "5242940"
  }
}
output {
  elasticsearch {
    hosts => "es:9200"
    index => "zc-logstash-%{+YYYY.MM.dd}"
  }
}

编辑flink-config.yaml文件

追加：

env.java.opts:  -Dlog4j2.formatMsgNoLookups=true
env.java.opts.taskmanager: -DyarnContainerId=$CONTAINER_ID
env.java.opts.jobmanager: -DyarnContainerId=$CONTAINER_ID

任务启动追加job名称

追加参数：env.java.opts=“-Dflink_job_name=DemoTask”
示例：

flink run -m yarn-cluster -d  -yjm 1024 -ytm 1048 -c cn.gwm.flink.streaming.task.DemoTask -yD env.java.opts="-Dflink_job_name=DemoTask"  -ynm  demoTask  /vmdata/flink/demoTask-lxy.jar
