> In the hadoop package distribution there are more than 90% of the jars are duplicated in multiple places.
> For Ex:
> almost all jars in share/hadoop/hdfs/lib are already there in share/hadoop/common/lib
> Same case for all other lib in share directory.
> Anyway for all the daemon processes all directories are added to classpath.
> So to reduce the package distribution size and the classpath overhead, remove the duplicate jars from the distribution.
