Marco Nicosia commented on HADOOP-2063:
---------------------------------------

I'm disappointed this didn't go in for Hadoop 0.16, despite having been set as target for 0.16. I understand that this is a pretty big change, but I really want to be sure we get something for Hadoop 0.17.

While we wait for this, any old Hadoop DFS' with corrupted files will need to sit, waiting for their owners to have a way to retrieve the files. For that time fsck will always return corrupt. The inability to do anything with these files (except delete them) could be masking us from being able to detect other hadoop issues.

>    Affects Versions: 0.14.1

> Before 0.14, dfs -get didn't perform checksum checking.   
> Users were able to download the corrupted files to see if they want to delete them.
> After 0.14, dfs -get also does the checksumming. 
> Requesting a command for no-checksum-get command.
