For various reasons, I have one hadoop installation on machine A, a second hadoop installation on cluster B, and a third hadoop installation on cluster C.
When I set up machine A, the xml files were set so that I could use the HDFS shell to find the HDFS on machine A.
I can rewrite the xml files on machine A so that the HDFS shell invoked from machine A sees a different HDFS by default.
However, I would like to be able to access all filesystems conveniently, without resetting the xml files.
Example: while logged in at machine A, I would like to copy a file from cluster B to cluster C with syntax something like:
hdfs dfs -cp hdfs://nn1.exampleB.com/file1 hdfs://nn2.exampleC.com/file2
Currently it seems that syntax does not work (although the errors are varied; sometimes they are EOF; other times they are network timeouts).
Should the above syntax be valid without modifications to the XML configuration files?
