Description

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
