Hive Filesystem

This is an attempt to make Hive look like just another filesystem from the Drake's point of view. Schemas are represented as "directories" and talbes as "files". Usage:

    hive://myserver:10000/stuff.cats <- /data/cat_movies.csv
        hive -e "LOAD DATA LOCAL INPATH '$INPUT' OVERWRITE INTO TABLE stuff.cats"

    hive://myserver:10000/stuff.new_releases <- hive://myserver:10000/stuff.cats 
        hive -e "INSERT OVERWRITE TABLE stuff.new_releases AS 
                     SELECT * FROM stuff.cats WHERE year=2013"

Please don't merge yet, as it is a work in progress.
