Siddharth Seth commented on MAPREDUCE-5310:
-------------------------------------------
Slot millis being computed by the MR AM isn't really correct. It was more of a
hack to maintain the counter. Between setting it to 0 and removing the counter
- I think removing it is a better option. It should really just be removed, but
concern with removing it is compatibility and whether anyone actually uses it.
> MRAM should not normalize allocation request capabilities
