Andrew Wang resolved MAPREDUCE-5620.
------------------------------------

    Resolution: Invalid

Turns out this was due to running distcp1 with hadoop 2's FsShell. I couldn't 
repro this on a pure branch-1 setup, so resolving as invalid.

> distcp1 -delete fails when target directory contains files with percent signs

> Debugging a distcp1 issue, it fails to delete extra files in the target 
> directory when there is a percent sign in the filename. I'm pretty sure this 
> is an issue with how percent encoding is handled in FsShell (reproduced with 
> just "hadoop fs -rmr"), but we can also fix this in distcp1 by using 
> FileSystem instead of FsShell. This is what distcp2 does.
