You know what I like about tar.gz? gzip is often a transparent compression layer on some tools, like say Athena. Tar is a simple concatenation of files + header. Therefore, even though Athena/Hive/Presto doesn't handle tar, I can use tar (or grep) to search the files without having to decompress them.
