             Summary: Configuring minimum-allocation-mb at queue level
                 Key: YARN-5900
                 URL: https://issues.apache.org/jira/browse/YARN-5900
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Manikandan R


Motivation for proposing minimum-allocation-mb at queue level in the form of 
yarn.scheduler.capacity.<queue-path>.minimum-allocation-mb
is, when the queue structure has been designed on resource usages (only memory for now). For example, there could be three segments like small, medium & large jobs and queues can be created for each segment accordingly. With this, it would be good to configure the min container size of each queue separately. For example, For small, it is 1 GB, For medium, it is 3 GB, For large, it can be 6 GB. 

Would this simplify container release process and its overall management, eventually reduces no. of containers running at any moment?
