Attachment: YARN-4597.005.patch
Updated patch v005 (also updated the Pull Request).

handled and does not happen:
bq. The logic to select opportunisitic container: we may kill more
opportunistic containers than required. e.g...
* Added some more javadocs and fixed some checkstyles.
* Rebased with trunk.
