-----------------------------

    Attachment: yarn-1197.pdf

Added a initial proposal for it, include increase/decrease a aquired or running container,
hope anybody can help me review it. Then we can move forward to break down tasks and start
work on it. Thanks.

which can make us incrementally ask resources, merge them to a bigger one, and launch our
processes. The user scenario is described in the comments.
