   Yeh, maybe a practicable solution, we can simply talk about it.
   
   Before submitting a yarn job, the client apply the application context from `RM` first, and get appId which will be then written into `NM`'s environment variable. We can use java agent to read it before executing yarn job's JAR file, also, can take `taskInstanceId` as input of agent program. However, where to store this mapping relationship need to be further considered. 
   
   Please let me know if you have any good suggestions!
