Hello Kun, Yes, this command works with federation. The command would copy the file from NameNode 1/block pool 1 to NameNode 2/block pool 2.

For example: ./bin/hdfs dfs -cp input1/a.xml input2/b.xml Supposed that input1 belongs namenode 1, and input 2 belongs namenode 2, does Federation support this operation? And if not, why? Thanks.
