documentation about Federated Namenodes[1], Datanodes can manage blocks from
multiple block pools – working with multiple Namenodes. This is indeed
reflected in the directory structure of the hdfs/data directory (described
here: [2]).
To configure a Datanode to talk to multiple Namenodes, one

Hi Genius,
I am currently involved in a project that will create/start multiple
