> Build a prototype of single task failure recovery to address and answer the
> following questions:

> upstream or downstream nodes.
> *Step 2*: Checkpointing part, as my understanding of how regional failover
> works, this part might not need modification.
> *Step 3*: Network part
> - how the recovered node able to link to the upstream ResultPartitions, and
> continue getting data
> - how the downstream node able to link to the recovered node, and continue
> getting node
> - how different netty transit mode affects the results
> - what if the failed node buffered data pool is full
