Summary: Lazy evaluate HiveMetastore::fireReadTablePreEvent table
computation
Key: HIVE-22725
URL: https://issues.apache.org/jira/browse/HIVE-22725
Project: Hive
Issue Type: Improvement
Reporter: Rajesh Balamohan
"TransactionalValidationListener" gets added in the pre-event listeners of HMS
by default.
[https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L559]
This causes issue in short select queries, as table details are computed for
any partition lookups.
[https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L4984]
It would be good to lazy evaluate table lookup in this codepath.
