Minor Description
Currently Hive outputs the result of "show grant" command in no deterministic order. It outputs the set of each privilege type in the order of whatever returned from DB (DataNucleus). Randomness can arise and tests (depending on the order) can fail, especially in events of library upgrade (DN or JVM upgrade). Sorting the result will avoid the potential randomness and make the output more deterministic, thus not only improving the readability of the output but also making the test more robust.
