Description

Running TestOperatorCmp, TestReOptimization currently in master (https://github.com/apache/hive/commit/10e5381cb6a4215c0b25fe0cda0a26a084ba6a89) shows BUILD SUCCESS although the tests are actually failing when executing the @BeforeClass logic.

Since the error appears inside @BeforeClass the failure remains unnoticed and the only indication that something is wrong is given by the INFO line below:

[INFO] Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

Steps to reproduce:

mvn test -Dtest=TestOperatorCmp
mvn test -Dtest=TestReOptimization
