2.yarn 的单作业运行模式

在 YARN 环境中，由于有了外部平台做资源调度，所以我们也可以直接向YARN 提交一个单独的作业，
从而启动一个 FLINK 集群。在客户端解析代码。

bin/flink run -d -t yarn-per-job -c com.ycl.WordCountStreamUnboundedDemo lib/FlinkTuTorial-1.17-1.0-SNAPSHOT.jar
这个方式启动后，客户端退出，不会影响正在执行的作业。

#分离模式启动;客户端启动后在后台运行，不会一直在前台界面停留。
bin/flink run -d -t yarn-per-job -d -c com.ycl.WordCountStreamUnboundedDemo lib/FlinkTuTorial-1.17-1.0-SNAPSHOT.jar

查看或者取消作业;
#查看作业
bin/flink list -t yarn-per-job -Dyarn.application.id=application_1782910361073_0001
#取消作业
bin/flink cancel -t yarn-per-job -Dyarn.application.id=application_1782910361073_0001 <jobId>

application_1782910361073_0001 是当前应用的ID,<JOBID> 是作业的ID,如果取消作业，整个flink集群也会停掉。
单作业模式，作业停止后，集群关闭了，同时作业状态变成:Finished; 资源会被回收。

#在分离模式下的一个问题，从flink1.13版本就有。
you can disable this check with the configuration 'classloader.check-leaked-classloader'.
#可以通过配置关闭这个报错。
vim flink-conf.yaml
classloader.check-leaked-classloader: false

再次运行作业，看是否报错。 可以看到已经没有报错了。 [flink@hadoop001 flink-1.17.0]$ bin/flink run -d -t yarn-per-job -c com.ycl.WordCountStreamUnboundedDemo lib/FlinkTuTorial-1.17-1.0-SNAPSHOT.jar SLF4J: Class path contains multiple SLF4J bindings.
