Review request for hive.


Minor update to the pom so the build can bootstrap.

Bugs: HIVE-860

Repository: hive-git


Caches auxiliary jars and remote runtime jars in /user/$user/.hiveJars by their sha1 hash.
This results in:

1) faster queries
2) less distributed cache churn
3) a smaller/cleaner hive-exec jar

Diffs (updated)

Tested manually on a cluster.
