1、用yarn 模式跑spark自带的example（就是算pi）的那个，可以成功。
2、用yarn 模式跑自己的spring boot项目失败（用local模式可以成功）。
3、 启动参数：./bin/spark-submit --class org.springframework.boot.loader.JarLauncher --master yarn --deploy-mode cluster --driver-memory 1g --executor-memory 2g --executor-cores 2 /home/hadoop/test-ks-1.0.0.jar
4、信息如下：

18/11/30 15:02:49 INFO yarn.Client: Application report for application_1543560852525_0004 (state: ACCEPTED)

。。。。。省略很多
