通过oozie job id可以查看流程详细信息，命令如下：
oozie job -info 0012077-180830142722522-oozie-hado-W

在yarn上可以看到application_1537326594090_5663对应的application如下
application_1537326594090_5663 hadoop oozie:launcher:T=spark:W=test_wf:A=test_spark_task:ID=0012077-180830142722522-oozie-hado-W Oozie Launcher
查看application_1537326594090_5663日志发现
2018-09-25 10:52:05,237 [main] INFO org.apache.hadoop.yarn.client.api.impl.YarnClientImpl - Submitted application application_1537326594090_5664
yarn上application_1537326594090_5664对应的application如下
application_1537326594090_5664 hadoop TestSparkTask SPARK
即application_1537326594090_5664才是Action对应的spark任务，为什么中间会多一步，类结构和核心代码详见 https://www.cnblogs.com/barneywill/p/9895225.html
简要来说，Oozie执行Action时，即ActionExecutor（最主要的子类是JavaActionExecutor，hive、spark等action都是这个类的子类），JavaActionExecutor首先会提交一个LauncherMapper（map任务）到yarn，其中会执行LauncherMain（具体的action是其子类，比如JavaMain、SparkMain等），spark任务会执行SparkMain，在SparkMain中会调用org.apache.spark.deploy.SparkSubmit来提交任务
