> Project: Tajo
> Issue Type: Bug
> Components: test
> Affects Versions: 0.10.0
> Reporter: Jongyoung Park
> Assignee: Jongyoung Park
> Priority: Blocker
> Attachments: TAJO-1440.log.bz2, TAJO-1440.patch, TAJO-1440_2.patch

>
> Running following command, test process often fails.
> bq. mvn clean install -Pparallel-test,hcatalog-0.12.0 -DLOG_LEVEL=ERROR
> -Dmaven.fork.count=2
> But it is not 100% failure rate.
> It looks like a concurrency problem.
> The reason why is :
> # When INFO instead of ERROR for log level is used, it doesn't seem that it
> happens.
> # Only it happens in parallel test.
> Usual failure spot is at TestKillQuery.
