Hello Friends,

         I have the following doubts.

Is the schedulers(Capacity Scheduler, Fair Scheduler, etc ) used in MR 1.x
are compatible with 2.x ?

If it is not compatible means, what are the
changes/modifications/difference between them?

I am working to implement a modified delay scheduling in HFS for 1.x
How it could be modified for 2.x versions?

What about Speculative Execution in MRv2. Is the any changes?

Help me in this regard. Thanks in advance.
