> Update for the description. Debugged more at this front based on the comments from Enis.

> The cause is that for the primary replica, if its retry is exhausted too fast, f.get()
[1] returns ExecutionException. This Exception needs to be ignored and continue with the replicas.
> The other issue is that after adding calls for the replicas, if the first completed task
gets ExecutionException (due to the retry exhausted), it throws the exception to the client[2].
> In this case, it needs to loop through these tasks, waiting for the success one. If no
one succeeds, throw exception.
> Similar for the scan as well
