> The DN should ignore {{allowLazyPersist}} hint to
> {{DataTransferProtocol#writeBlock}} if the writer is not local.
> Currently we don't restrict memory writes to local clients. For in-cluster
> clients this is not an issue as single replica writes default to the local
> DataNode. But clients outside the cluster can still send this hint.
