> HADOOP-6421 added symbolic links to FileContext. Resolving symlinks is done on the client-side, and therefore requires client support. An HDFS symlink (created by FileContext) when accessed by FileSystem will result in an unhandled UnresolvedLinkException. Because not all users will migrate from FileSystem to FileContext in lock step, and we want users of FileSystem to be able to access all paths created by FileContext, we need to support symlink resolution in FileSystem as well, to facilitate migration to FileContext.
