Description

Trying to create a symlink to another file that is specified for the distributed cache will fail to create the link. For example:

hadoop jar ... -files "x,y,x#z"

will localize the files x and y as x and y, but the z symlink for x will not be created. This is a regression from 1.x behavior.
