Jason Lowe commented on MAPREDUCE-4980: --------------------------------------- I'm not sure adding more time to TestMapReduceJobControl is going to help, as it looked like a surefire timeout rather than a junit timeout. MAPREDUCE-6747 is tracking the issue. What I believe is happening is that the code is trying to kill a local job (which involves trying to interrupt a thread) and that interrupt gets swallowed at some point. It then spins waiting for a job to exit that isn't going to exit since it wasn't successfully interrupted. Eventually surefire steps in and kills the whole mess without a lot of helpfulness. For this JIRA I'd be tempted to slap a reasonable junit timeout on testJobControlWithKillJob so we don't wait the full surefire timeout when it is going to hang. We can fix that test in MAPREDUCE-6747. Still haven't been able to reproduce the TestNNBench issue, but I've only been able to take a couple of cracks at it in my spare time. Will try to get a few more tries in the next few days. > Parallel test execution of hadoop-mapreduce-client-core > ------------------------------------------------------- > > Key: MAPREDUCE-4980 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4980 > Project: Hadoop Map/Reduce > Issue Type: Test > Components: test > Affects Versions: 3.0.0-alpha1 > Reporter: Tsuyoshi Ozawa > Assignee: Andrey Klochkov > Attachments: MAPREDUCE-4980.010.patch, MAPREDUCE-4980.011.patch, > MAPREDUCE-4980.012.patch, MAPREDUCE-4980.013.patch, MAPREDUCE-4980.014.patch, > MAPREDUCE-4980.1.patch, MAPREDUCE-4980--n3.patch, MAPREDUCE-4980--n4.patch, > MAPREDUCE-4980--n5.patch, MAPREDUCE-4980--n6.patch, MAPREDUCE-4980--n7.patch, > MAPREDUCE-4980--n7.patch, MAPREDUCE-4980--n8.patch, MAPREDUCE-4980.patch > > > The maven surefire plugin supports parallel testing feature.
