> Key: HIVE-20986
> URL: https://issues.apache.org/jira/browse/HIVE-20986
> Project: Hive
> Issue Type: Improvement
> Reporter: Karthik Manamcheri
> Assignee: Adam Holley
> Priority: Major
>
> 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.
