Dhruv Mahajan commented on REEF-1224:
-------------------------------------

I meant at theoretical or understanding level its not an issue...But When I actually think
of how to implement I need some better understanding that comes by looking at code and examples.

> Currently in IMRU, data downloading happens during the Task injection. It couples the
data and Task object. In Fault tolerant case, we would like to only resubmit a task but use
the data that have been downloaded, That requires us to decouple those two portions. For example,
data downloading portion can be attached to Context, and we can then resubmit a task on the
same context.
