Setting it per queue will help > prevent abuse, help limit the impact of reservations, and allow changes in > the maximum container size to be rolled out more easily. > One reason this is needed is more application types are becoming available on > yarn and certain applications require more memory to run efficiently. While > we want to allow for that we don't want other applications to abuse that and > start requesting bigger containers then what they really need. > Note that we could have this based on application type, but that might not be > totally accurate either since for example you might want to allow certain > users on MapReduce to use larger containers, while limiting other users of > MapReduce to smaller containers. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
