Ted Malaska updated MAPREDUCE-5132:
-----------------------------------
Attachment: FairSchedulerPlusCode.zip
Here is a sample of extending the existing FairScheduler.
Please let me know what you think.
> Enhance FairScheduler queue selection with Unix-SubGroups
> ---------------------------------------------------------
>
> Key: MAPREDUCE-5132
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-5132
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Reporter: Ted Malaska
> Priority: Minor
> Attachments: FairSchedulerPlusCode.zip
>
>
> I have clients that use the primary group for other reasons and would like to
> select the fairScheduler queue by subgroup.
> Currently the fairscheduler can only link a job config property to a
> fairscheduler queue and subgroups are not in the job config.
> Now thankfully we can get this data from UserGroupInformation.createProxyUser
> which is cool because this is how TT currently see if it can copy data when
> kerberos is enabled. Once we have the sub-groups we just connect the first
> sub-group that matches a queue.
> I'll put up some code that I used to solve the problem in the short term.
> Note that there is an issue with this code. It doesn't populate the TT Web
> UI drop down menu correctly. I think I have a solution for that, but before
> I implement that I was wondering if the community has any feedback first.
