本地Eclipse提交MR程序到Yarn

1、一般地，从Windows本地的Eclipse提交程序到yarn，会报如下错误：

Diagnostics: Exception from container-launch.
Container id: container_1526537597068_0006_02_000001Exit code: 1Exception message: /bin/bash: line 0: fg: no job control

Container exited with a non-zero exit code 1

2、原因：
客户端提交任务时候，在YARNRunner.java中调用了  createApplicationSubmissionContext方法，该方法负责初始化启动MRAppMaster的脚本，该脚本的生成依赖于本地系统，而目前由于是在Windows系统下，所以生成的脚本提交到Linux集群上运行必然出错。

createApplicationSubmissionContext

3、手工修改YARNRunner适配Linux系统，

// Construct necessary information to start the MR AM
        ApplicationSubmissionContext appContext = createApplicationSubmissionContext(conf, jobSubmitDir, ts);

4、修改完再次运行debug看到appContext的值为：
