Lin Yiqun commented on MAPREDUCE-6548:
--------------------------------------
Thanks [[email protected]] for comments.I have ignored some other influence of
hive or spark on yarn,. That's a good idea to create a special queue for
critical jobs now.But I thinks maybe we can do some admission control for jobs
in some other aspects in the future.
> Jobs executed can be configurated with specific users and time hours

> Project: Hadoop Map/Reduce

> 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.
