Flink(二) —— 部署与任务提交

一、下载&启动

官网上下载安装包,执行下列命令即启动完成。

./bin/start-cluster.sh

效果图

Flink部署模式

  • Standalone模式
  • Yarn模式
  • k8s部署

二、配置文件

flink-conf.yaml


# The number of task slots that each TaskManager offers. Each slot runs one parallel pipeline.

taskmanager.numberOfTaskSlots: 4

# The parallelism used for programs that did not specify and other parallelism.

parallelism.default: 1

三、提交任务

以UI的方式提交

以命令的方式提交

提交job

./flink run -c flink.StreamWordCount -p 2 myspark-1.0-SNAPSHOT.jar

查看当前所有job

> flink list

Waiting for response...
------------------ Running/Restarting Jobs -------------------
21.02.2020 03:35:27 : 97e8af8af740098de8e80a8aedd16839 : stream word count (RUNNING)
--------------------------------------------------------------
No scheduled jobs.

取消job

./flink cancel 97e8af8af740098de8e80a8aedd16839

异常

同样的代码,同样的操作,该异常只有在windows上部署的时候,才会出现问题,在MacBook上则是正常的。

java.util.concurrent.CompletionException: 
org.apache.flink.runtime.jobmanager.scheduler.NoResourceAvailableException: 
No pooled slot available and request to ResourceManager for new slot failed
