Nemanja Matkovic commented on MAPREDUCE-6519: --------------------------------------------- TL; DR; I think we can commit this patch as it doesn't introduce regressions Two QA bot runs are running identical code, only two test cases with same failure are: * hadoop.mapreduce.v2.TestMRJobsWithHistoryService * hadoop.mapred.TestMiniMRClientCluster Both of these have very wild history full of reds and blues in pass/fail chart. In order to be good citizen (and sleep better at night) I went back and re-ran all these failed tests locally on java 7 and java 8 (named java7 and java8 below). I also ran them all on both java 7 and java 8 without any of IPv6 changes (head being eb6379ca25e1bb6d3978bd3a021723c38c95bec9). These are named base_java7 and base_java8 below. These are local results I have and investigation of history of these test cases that I saw: * hadoop.mapreduce.filecache.TestClientDistributedCacheManager ** java7, java8, base_java7, base_java8: FAIL. This is consistently failing because it fails here: "Assert.assertFalse(jobConf.getBoolean(MRJobConfig.CACHE_FILE_VISIBILITIES,true));" and I haven't changed this configuration. * hadoop.mapreduce.v2.TestMRJobsWithProfiler ** java7, base_java7: Pass ** java8, base_java8: Fail ** Consistent behavior, no regression ** There is no history data for this test case * hadoop.mapred.TestMiniMRClientCluster ** java7, base_java7: Fail ** java8, base_java8: Pass ** Consistent behavior, not regression ** History data shows lots of flakiness with same failure * hadoop.mapreduce.v2.TestMRJobs ** java7, java8, base_java7, base_java8: Pass ** Failure in QABot run looks strange, but similar to the way other flaky tests are failing * hadoop.mapreduce.v2.TestNonExistentJob ** java7, java8, test_java7, test_java8: PASS ** There is one previous run QA bot with same failure, so very occasional flakyness * hadoop.mapreduce.v2.TestUberAM * java7, java8, base_java7: Pass * base_java8: Timeout * No regression * hadoop.mapreduce.v2.TestMRJobsWithHistoryService ** java7: Multiple runs got both pass and fail locally ** java8: Pass ** base_java7: Fail ** base_java8: Pass ** Test historically flaky > hadoop-mapreduce - Avoid unsafe split and append on fields that might be IPv6 > literals > -------------------------------------------------------------------------------------- > > Key: MAPREDUCE-6519 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6519 > Project: Hadoop Map/Reduce > Issue Type: Task > Reporter: Nemanja Matkovic > Assignee: Nemanja Matkovic > Labels: ipv6 > Attachments: MAPREDUCE-6519-HADOOP-11890.1.patch, > MAPREDUCE-6519-HADOOP-11890.2.patch > > Original Estimate: 48h > Remaining Estimate: 48h > > mapreduce portion of patch in HADOOP-12122 that couldn't run due to number of > components touched. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
