Subject Re: Build failed in Jenkins: HBase-0.94 #589
Date Wed, 14 Nov 2012 19:55:55 GMT
Sigh.

It seems we're back at having a successful build being the exception rather than the rule.
In this case it was some(?) timeout (all tests ran and passed), but many previous runs had
at least one test failing.

Flaky tests are useless. They do not add confidence to a run, and worse they add noise, which
requires us to manually filter the good from the bad runs but looking at the results.

There was talk about separating the flaky tests from the good ones.
Short term I propose to disable or remove every test that failed more than once in the last
10 runs.


This is getting quite frustrating.
