Subject [jira] [Commented] (SOLR-9181) ZkStateReaderTest failure
Date Sun, 03 Jul 2016 20:34:11 GMT


Steve Rowe commented on SOLR-9181:

Around the cefab1dfff commit under this issue, my Jenkins master Lucene/Solr test job went
from about 50% overall job failure rate (i.e. at least one test failure in a run - this unfortunately
has been the case for quite some time) to nearly 100% failures (28 runs with at least one
failure out of 29 runs) - see the trend here <>.
 I think Policeman and ASF Jenkins are seeing increases in failure rates too but I haven't
counted yet. The few failing tests I attempted with don't reproduce.  The ZK reader and writer
tests seem to be failing quite a bit more often now, but that's anecdotal; I didn't look at
the numbers.  

So I stopped all other jobs on my Jenkins and did a brute force search for which commit to
blame, by pinning 7 jobs each at a different non-trivial commit in the suspect time frame
- you can see these jobs here: <>.  Each job
has run about 20 times now, and c3fab1dfff stands out as failing signficantly more often:
