Wei Yan updated YARN-2618:
--------------------------
Attachment: YARN-2618-2.patch
Thanks, [~kasha]. Update a new patch to fix the comments.
The existing patch works well with FairScheduler. But for FifoScheduler and
CapacityScheduler, it cannot avoid over-allocating disk resources. This is
because both Fifo and Capacity only care memory capacity when assigning
containers to nodes, and support over-consuming for cpu resources. [~jianhe],
do u know any special reason why CapacityScheduler support over-consuming cpu
resources?
