-------------------------------------------------------------
[~leftnoteasy], [~liuxun323] , While refining the patch, I found that YARN
localizer seems can localize *remote directory(hdfs, s3 .etc)*. In
FSDownload.java#downloadAndUnpack, it uses "FileUtil.copy" which can handle
directory.
Depending on this can greatly simplify our implementation, no need to download
remote dir or zip local dir anymore.
We may still need a configuration to limit the remote file/dir size to be
localized to the container.
I will verify and update the patch tomorrow.
