------------------------------------
Summary: [MINOR] [JDBC] JDBCInterpreterTest.testMultiTenant_*
improvement
Key: ZEPPELIN-5816
URL: https://issues.apache.org/jira/browse/ZEPPELIN-5816
Project: Zeppelin
Issue Type: Improvement
Reporter: Guanhua LI
Assignee: Guanhua LI
Now In test cases `JDBCInterpreterTest.testMultiTenant_1` and
`JDBCInterpreterTest.testMultiTenant_1`, the jdbc interpreter would try to
connect h2 databases with 3 non-existed user.
It would cost more time to execute these two test case.
And also the interpreter would log a long message about
`JdbcSQLInvalidAuthorizationSpecException` , which may mislead developer who is
unfamiliar to JDBC module into thinking there is something wrong with the test
case。
