Is there a way to resolve Fair Scheduler Problem

[mahender bigdata]

Hi Team,

Is there way to resolve Fair Queue Scheduler problem. Currently I see 
If  application requires more resources, it fully consumes available 
resources leaving other submitted applications in *pending *or *accepted 
*state. Do i need to modify
set yarn.scheduler.maximum-allocation-mb=5120;
set yarn.scheduler.minimum-allocation-mb=512;
or

Yarn scheduler Queue capacity needs to be modified.

Thanks.
