Eric Lin commented on HIVE-16029:
---------------------------------
Hi [~appodictic],
Thanks for the suggestion. I am trying to run the test for TestCliDriver using
below command under directory itests/qtest by following the documentation
https://cwiki.apache.org/confluence/display/Hive/HiveDeveloperFAQ#HiveDeveloperFAQ-Testing:
{code}
mvn test -Dtest=TestCliDriver
{code}
However, it kept failing with below error:
{code}
