> The issue is that we came across a ReplicaNotFoundException in a bug report, the most
informative thing we could get is "Replica not found for [ExtendedBlock]". If someone tries
to investigate cases including ReplicaNotFoundExceptions should review diagnostic bundles,
dig through logs, but as a starting point enhancing the exception message would boost this
process, and be beneficial in the long run.
> More concretely, it would be helpful if any of the following information was displayed
along with the exception: file's name, replication factor or block location.
