Devaraj Das updated MAPREDUCE-744:
----------------------------------
Attachment: 744-early.patch
Attaching a preliminary patch for review. What's done there is that the cache
files are checked at the client side for public/private access, and that
information (booleans - true for public, false for private) is passed in the
configuration. The TaskTrackers look at the configuration for each file during
localization, and, if the file was public they localize it to a common space.
If not, then the file is localized to the user's private directory.
Testcase is not there yet.
