> User has to create a third set of configuration files for distcp when
> transferring data between two HA clusters.
> Consider the scenario in [1]. You cannot put all of the required properties
> in core-site.xml and hdfs-site.xml for the client to resolve the location of
> both active namenodes. If you do, then the datanodes from cluster A may join
> cluster B. I can not find a configuration option that tells the datanodes to
> federate blocks for only one of the clusters in the configuration.
