             Summary: In DistCp, prevent unnecessary getFileStatus call when 
not preserving metadata.
                 Key: HADOOP-13145
                 URL: https://issues.apache.org/jira/browse/HADOOP-13145
             Project: Hadoop Common
          Issue Type: Improvement
          Components: tools/distcp
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth


After DistCp copies a file, it calls {{getFileStatus}} to get the 
{{FileStatus}} from the destination so that it can compare to the source and 
update metadata if necessary.  If the DistCp command was run without the option 
to preserve metadata attributes, then this additional {{getFileStatus}} call is 
wasteful.
