Distcp between CDH3 and CDH4

Assume aa is CDH3 and dev is CDH4:

Run this on jobs-aa
hadoop distcp hftp://jobs-aa-hnn/root/my/dir hdfs://jobs-dev-hnn/root/my/dir

Reverse direction:


hadoop distcp hdfs://jobs-dev-hnn:50070/root/my/dir hdfs://jobs-aa-hnn/root/my/dir
(got to have this port number because CDH4 requires that)
