Just an FYI as a side affect of HADOOP-9765 - "Precommit Admin job chokes on issues without an attachment" being committed, HiveQA execution latencies should be reduced dramatically because we no longer have to interact with the Apache Jenkins pool.
Once the Precommit-Admin job finds a Hive patch in need of testing it sends it directly to the Bigtop Jenkins which almost always has available executors.
