Wei-Chiu Chuang commented on HDFS-13140:
----------------------------------------

Hi [~abhishekbafna] thanks for filing the Jira & contributing the patch.

Would you please:
 # Update Jira description to explain what does it do? I.e. in addition to an 
overall description, please explain how your patch does what it claims to do.
 # You need a unit test for the new capability added in the patch.
 # It seems the patch has some caveats. E.g. If the destination file system is 
not HDFS-based, it does not verify the destination is not changed. Is that a 
valid assumption?
 # What cloud storage system has been tested against it?
 # Any limitation?
