> 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
