In the discussions with a few developers, we have some new thoughts about the resource config and packing algorithms in heron. Basically we want to step back from the current configs and try to come up with a new solution from user's point of view.
Here is a brief proposal document for reference and discussion. https://docs.google.com/document/d/1huySPugRcR5LXmlBxCCtie9grkc-X67t57_R_tZM-4w/edit# Please feel free to comment. Thanks in advance. Regards, --ning
