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

Yes...Mainly I am planning to introduce re-try logic in Link and StreamingLink. I tried it
and it works. I will send JIRA for it. However, I am confused why it does not happen if we
introduce Network Service as separate Service Layer.

> 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.
