Sean Owen commented on SPARK-14486:
-----------------------------------

[~meiyoula] this sounds like you want to initiate a discussion. I'm not clear what you're
concretely proposing here. JIRAs are really for when you can describe a specific change and
reasons for it.

> For partition table, when partition rdds do some maps, the rdd number will multiple grow.
So rdd number in dag will become thounds, and occurs oom.
> Can we make a improvement to reduce the rdd number in dag. show the same rdds just one
time, not each partition.
