Can you tell me the exact command to import data from hdfs with two different haddop version one with hadoop 2.0.4 alpha and other 2.4.0 version? How can I use distcp command in this case?
When you have different versions use hftp instead of using the actual hdfs command. You can see examples on Cloudera website. Use the hftp on your source cluster and hdfs on your destination cluster address.
