----------------------------------------
I am deferring this to Hive 3.0 as we are going to cut the first RC and it is
not marked as blocker. Please feel free to commit to the branch if this can be
resolved before the release.

> In most cases, the UGI can be re-used across different fragments - since the
> data is owned by Hive. This can cut down the number of connections
> established to datanodes / the namenode.
