[jira] [Created] (HADOOP-18056) DistCp: Filter duplicates in the source paths

Ayush Saxena created HADOOP-18056:
-------------------------------------

             Summary: DistCp: Filter duplicates in the source paths
                 Key: HADOOP-18056
                 URL: https://issues.apache.org/jira/browse/HADOOP-18056
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Ayush Saxena
            Assignee: Ayush Saxena


Add a basic filtering to remove the exact duplicate paths exposed for copying.

In case two same srcPath say /tmp/file1 is passed in the list twice. DistCp fails with DuplicateFileException, post building the listing.

Would be better if we do a basic filtering of duplicate paths.
