unit tests fail consistently when run according to instructions on "hive how to

-------------------------------------------------------------------------------------------------
Key: HIVE-2174
URL: https://issues.apache.org/jira/browse/HIVE-2174
Project: Hive
Issue Type: Bug
Components: Build Infrastructure, Testing Infrastructure
Affects Versions: 0.7.1, 0.8.0
Reporter: Patrick Hunt
Priority: Critical
The unit tests fail consistently when run according to the doc on hive how to
contribute page. Specifically if you:
1) checkout the code afresh (or 'git clean -xdf' - basically be sure to start
with a _very_ clean slate)
2) ant clean test tar -logfile ant.log
the tests will fail (you can run just bucketmapjoin1.q instead of all the
tests, it exhibits this behavior). However if you instead do the following
2) ant clean package test tar -logfile ant.log
the tests pass (notice the addition to package to the targets).
I've tried this on 5 different systems (mix of linux 32/64 bit) and the result
is consistent.
Running
ant clean test -Dtestcase=TestCliDriver -Dqfile=bucketmapjoin1.q
I see the following reason for failure

which leads me to believe it's a metastore issue (statistics?)
