> The distributed cache does not work like it does in 1.0.
> mapreduce.job.cache.symlink.create is completely ignored and symlinks are always created no matter what. Files and archives without a fragment will also have symlinks created.
> If two cache archives or cache files happen to have the same name, or same symlink fragment only the last one in the list is localized.
> The localCacheArchives and LocalCacheFiles are not set correctly when these duplicates happen causing off by one or more errors for anyone trying to use them.
> The reality is that use of symlinking is so common currently that these incompatibilities are not that likely to show up, but we still need to fix them.
