Arpit Agarwal commented on HDFS-13502:
--------------------------------------

Thanks for filing this [~apoorvnaik]. We can potentially expose this mapping via HdfsUtils,
which is a public interface.

> A Utility class in HDFS, that would act as a reverse lookup for <host>:<port>
HDFS URLs would be beneficial for deployments having multiple namenodes and nameservices.
>  
> Consumers would benefit by having a unified namespace across the Federated cluster.
