---------------------------------
No. I guess we still need this jira for adding the striped block logic and the
tests.
> Erasure Coding: revisit replica counting for striped blocks

> Currently we use the same {{BlockManager#countNodes}} method for striped
> blocks, which simply treat each internal block as a replica. However, for a
> striped block, we may have more complicated scenario, e.g., we have multiple
> replicas of the first internal block while we miss some other internal
> blocks. Using the current {{countNodes}} methods can lead to wrong decision
> in these scenarios.
