After i kill a app by typing "bin/yarn rmadmin app -kill APP_ID",
no job info is kept on JHS web page.
However, when i kill a job by typing " bin/mapred job -kill JOB_ID" ,
i can see a killed job left on JHS.
Some hive users are confused by that their jobs been killed but nothing left on JHS ,and killed app's info on RM web page is not enough.(They kill job by clientRMProtocol)
