Running following command, test process often fails.
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.
