{code}
I believe the problem is this line of code:
{code}
if check_stack_feature(StackFeature.HIVE_SERVER_INTERACTIVE,
stack_version_unformatted):
{code}
On a downgrade from 2.5 to 2.3 {{version}} and {{current_version}} are pointing
to 2.3, but stack_version_unformatted is still 2.5. Because of this, we
initialize the hive2 variables which leads us to think that hive2 is the target
of copying the JDBC:
{code}
if name == 'metastore' or name == 'hiveserver2':
if params.hive_jdbc_target is not None and not
os.path.exists(params.hive_jdbc_target):
jdbc_connector(params.hive_jdbc_target, params.hive_previous_jdbc_jar)
if params.hive2_jdbc_target is not None and not
os.path.exists(params.hive2_jdbc_target):
jdbc_connector(params.hive2_jdbc_target, params.hive2_previous_jdbc_jar)
{code}
