I see a continuing pattern of jobs failing on Jenkins. This happens with
Mahout-Quality and Drill-Physical-Plan. Both jobs are totally stable on
other platforms and do not involve non-deterministic tests. In any case,
these failures can occur long before the tests even start. Failures seem
to occur for Mahout-Quality about 20% of all attempts. There is also a
lower rate issue in which the build times out after taking much longer than
usual.
The stack trace for the first kind of failure generally looks something
like the trace below.
Does anybody have any idea what is going on?
My feeling is that a build system that fails more often than the software
being tested is just misleading and not worth much.
