Lin Yiqun updated MAPREDUCE-6548: --------------------------------- Status: Patch Available (was: Open) I attach a initial patch.I do some user-check and time-check in job submission methods {{Job#submit}} and {{Job#waitForCompletion}}. And I add the 3 new config as below. * MAPREDUCE_LIMIT_EXECUTED_ENABLED:whether enable the limit-executed function. * MAPREDUCE_LIMIT_EXECUTED_USERS:the user that can be executed in cluster. * MAPREDUCE_LIMIT_EXECUTED_HOURS:the job can be executed in these hours in this config value. > 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 > > 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)
