             Summary: FairScheduler handles "dots" in user names inconsistently 
in the config
                 Key: YARN-5674
                 URL: https://issues.apache.org/jira/browse/YARN-5674
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 2.6.0
            Reporter: Wilfred Spiegelenburg
            Assignee: Wilfred Spiegelenburg


A user name can contain a dot because it could be used as the queue name we 
replace the dot with a defined separator. When defining queues in the 
configuration for users containing a dot we expect that the dot is replaced by 
the "\_dot\_" string.
In the user limits we do not do that and user limits need a normal dot in the 
user name. This is confusing when you create a scheduler configuration in some 
places you need to replace in others you do not. This can cause issue when user 
limits are not enforced as expected.

We should use one way to specify the user and since the queue naming can not be 
changed we should also use the same "\_dot\_" in the user limits and enforce 
correctly.
