Bikas Saha commented on MAPREDUCE-6548: --------------------------------------- Does the admission control added to YARN help this scenario? YARN-1051. The important job could be guaranteed its capacity between 0 to 9am using admission control. > Jobs executed can be configurated with specific users and time hours > -------------------------------------------------------------------- > > Key: MAPREDUCE-6548 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6548 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: job submission > Reporter: Lin Yiqun > Assignee: Lin Yiqun > Attachments: MAPREDUCE-6548.001.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
