Reynold Xin commented on SPARK-10000:
-------------------------------------

[~bowenzhangusa]  thanks for the interest. This task is pretty significant and 
involves substantial refactoring to internals, so it might be pretty hard for 
somebody less familiar with Spark to just pick up. However, we will post a 
design doc soon and try to break this down into multiple tasks. Please follow 
the ticket and see if you can help contribute to some of them. Thanks!

> As a Spark user, I want Spark to manage the memory more intelligently so I do

> memory fraction and cache memory fraction.
