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

             Summary: Distcp cannot copy files of the same name in different directories
                 Key: MAPREDUCE-7096
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7096

          Issue Type: Bug
          Components: distcp
    Affects Versions: 2.7.3
            Reporter: tangshangwen


When I tested distcp, I found that I could not copy files with the same name in different
directories,here is my test case:

source:
/user/hadoop/dir1/a.txt
/user/hadoop/dir2/a.txt

target
/tmp/dist-cp/


hadoop distcp -m 2 -overwrite /user/hadoop/dir* /tmp/dist-cp/

result: failed


source:
/user/hadoop/dir1/a.txt
/user/hadoop/dir2/b.txt

target:
/tmp/dist-cp/


hadoop distcp -m 2 -overwrite /user/hadoop/dir* /tmp/dist-cp/

result: success
