> Pig currently copies jar files to a temporary location in hdfs and then adds them to
DistributedCache for each job launched. This is inefficient in terms of 
>    * Space - The jars are distributed to task trackers for every job taking up lot of
local temporary space in tasktrackers.
>    * Performance - The jar distribution impacts the job launch time.
