> 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
