hadoop dfs -cp foo/bar/bad-file mumble/new-file copies a file with a bad checksum
---------------------------------------------------------------------------------

                 Key: HADOOP-518
                 URL: http://issues.apache.org/jira/browse/HADOOP-518
             Project: Hadoop
          Issue Type: Bug
          Components: dfs
         Environment: red hat
            Reporter: Dick King


I have a file that reliably generates a checksum error when it's read, whether by a map/reduce
job as input or by a "dfs -get" command.

However...

if I do a "dfs -cp" from the file with the bad checksum the copy can be read in its entirety
without a checksum error.

I would consider it reasonable for the command to fail, or for the new file to be created
but to also have a checksum error in the same place, but this behavior is unsettling.
