xloya opened a new issue #3796:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/3796


   Recently, I looked at the code of the job status on YARN after the job was 
submitted and got the job status on the YARN.When I saw 
incubator-dolphinscheduler/dolphinscheduler-server/src/main/java/org/apache/dolphinscheduler/server/worker/task/AbstractCommandExecutor.java
 , I found a method named isSuccessOfYarnState(List<String> appIds).Why here is 
a list of appid?I think log file is one-to-one with yarn app.I really hope to 
get the answer, thx!
   
   
最近我在看作业提交到yarn之后,获取yarn上作业状态的代码.当我看到incubator-dolphinscheduler/dolphinscheduler-server/src/main/java/org/apache/dolphinscheduler/server/worker/task/AbstractCommandExecutor.java这个类时,有个方法叫isSuccessOfYarnState(List<String>
 appIds).为什么这里会是一个appid的列表?我理解的log文件应该跟app是一对一的.非常希望得到解答,谢谢!
