--------------------------------------

             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.
