Shawn Heisey updated SOLR-12429:
--------------------------------
Description:
If a configset being uploaded to ZK contains a symlink pointing at a directory,
an error is thrown, but it doesn't explain the real problem. The upconfig
should detect symlinks and throw an error indicating that they aren't
supported. If we can detect any other type of file that upconfig can't use
(sockets, device files, etc), the error message should be relevant.

I have not tested whether a symlink pointing at a file works, but I think that
an error should be thrown for ANY symlink.
