Lin Yiqun updated MAPREDUCE-6548:
---------------------------------
Description: In recent hadoop versions,the system has no limitation for
users to execute their jobs if you don't configurate ACL.And I find that the
ACL is only called in IPC, isn't operated in job submissions.And this condition
can't satisfied with this case that I have a very important job, and I am
prepared to execute this job in 0 to 9 o'clock.In order to let this job
executed quickly, I am not allowed other user's job to execute in these time.
So I can see the result in tomorrow morning.So may be we can let jobs executed
with specific users in specific time hours. (was: In recent hadoop
