Summary: Add TransactionalValidationListener to HMS preListeners
only when ACID support is enabled
Key: HIVE-20986
URL: https://issues.apache.org/jira/browse/HIVE-20986
Project: Hive
Issue Type: Improvement
Reporter: Karthik Manamcheri
Assignee: Adam Holley
We add the TransactionalValidationListener to the preListeners in HMS
unconditionally.
{code:java}
public void init() throws MetaException {
..
preListeners.add(0, new TransactionalValidationListener(conf));
..
}{code}
This causes some performance issues because the listener is called even when
not needed. Lets add a condition around this and add this listener only if the
transactional support is enabled.
