【Flink源码】二、客户端是否以yarn模式提交

一、在验证是否活跃提交模式里面

 

public boolean isActive(CommandLine commandLine) {
　　　　　　　　　 //命令行是否有 yarn-cluster
		final String jobManagerOption = commandLine.getoptionValue(addressOption.getopt(), null);
		final boolean yarnJobManager = ID.equals(jobManagerOption);
　　　　　　　　　 //命令行里面是否有appid,配置里面是否有appid  application_1623987801507_0002
		final boolean hasYarnAppId = commandLine.hasOption(applicationId.getopt())
			|| configuration.getoptional(YarnConfigOptions.APPLICATION_ID).isPresent();
                //配置里面是否有执行器是基于yarn
		final boolean hasYarnExecutor = YarnSessionClusterExecutor.NAME.equalsIgnoreCase(configuration.get(DeploymentOptions.TARGET))
			|| YarnJobClusterExecutor.NAME.equalsIgnoreCase(configuration.get(DeploymentOptions.TARGET));
		return hasYarnExecutor || yarnJobManager || hasYarnAppId;
	}

　　

YarnSessionClusterExecutor.NAME里面有这三个

        PER_JOB("yarn-per-job"),
	SESSION("yarn-session"),
	APPLICATION("yarn-application");

　　这三个条件有一个，走yarn模式提交
