[jira] [Comment Edited] (YARN-1655) Add implementations to
FairScheduler to support increase/decrease container resource
[ https://issues.apache.org/jira/browse/YARN-1655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16764807#comment-16764807 ]

Adding resizing to the FS.
Some background around the changes outside the FS:
# the {{RMContainerImpl}} logs a message when the temporary containers for resizing are released because they are in the wrong state. The new transitions clean those up
# Normalising requests has been moved from the {{CapacityScheduler}} into the {{AbstractYarnScheduler}} as it is used by both schedulers.
# Resizing would only use the ANY request and leave node and rack requests hanging around which caused the FS to allocate strange containers. {{AppSchedulingInfo}} now allows for cleaning up the unneeded requests from the {{ContainerUpdateContext}}
