Description

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 :

1. When INFO instead of ERROR for log level is used, it doesn't seem that it happens.
2. Only it happens in parallel test.

Usual failure spot is at TestKillQuery.
