Ashutosh informed me that the precommit build was hung. Long story short, PTest2 had completed. For example, see this job which took 8 hours:
http://bigtop01.cloudera.org:8080/job/PreCommit-HIVE-Build/1636/ That correpsonds to: http://ec2-174-129-184-35.compute-1.amazonaws.com/logs/PreCommit-HIVE-Build-1637/execution.txt which if you scroll all the way to the bottom, you will note it finished long before that: 2014-03-06 05:48:22,194 INFO PTest.run:207 Executed 5358 tests 2014-03-06 05:48:22,194 INFO PTest.run:209 PERF: Phase ExecutionPhase took 101 minutes 2014-03-06 05:48:22,194 INFO PTest.run:209 PERF: Phase PrepPhase took 5 minutes 2014-03-06 05:48:22,194 INFO PTest.run:209 PERF: Phase ReportingPhase took 0 minutes 2014-03-06 05:48:22,194 INFO JIRAService.postComment:136 Comment: {color:red}Overall{color}: -1 at least one tests failed .... Long story short, it looks like Bigtop Jenkins is not as reliable as we would like.
