             Summary: Fix tests failing due to invalid ConnectionDriverName
                 Key: HIVE-12670
                 URL: https://issues.apache.org/jira/browse/HIVE-12670
             Project: Hive
          Issue Type: Bug
            Reporter: Mohit Sabharwal
            Assignee: Mohit Sabharwal


Some unit tests fail when run outside the ptest environment (i.e. when run individually on the local box like mvn test -Dtest=TestSessionHooks) with the following error:

{code}
Caused by: org.datanucleus.exceptions.NucleusException: Attempt to invoke the "BONECP" plugin to create a ConnectionPool gave an error : The specified datastore driver ("hive-site.xml") was not found in the CLASSPATH. Please check your CLASSPATH specification, and the name of the driver.
{code}

This is because to support TestHiveConf, we override {{javax.jdo.option.ConnectionDriverName}} in  test hive-site file (common/src/test/resources/hive-site.xml). However, this override gets applied for all tests. The overriden value is invalid, which causes other tests that attempt to initialize CliService to fail.

Instead, we should use a property exclusively used for testing like {{hive.test.dummystats.aggregator}} so that overriding it does not affect other tests.

Not sure why these tests pass in ptest, presumably because some other test that comes before overrides {{javax.jdo.option.ConnectionDriverName}} to a sensible value.

Tests failing:

TestSessionHooks
TestPlainSaslHelper 
TestSessionGlobalInitFile
