Summary: Improve HiveMetaStoreClient.dropDatabase
Key: HIVE-18705
URL: https://issues.apache.org/jira/browse/HIVE-18705
Project: Hive
Issue Type: Improvement
Reporter: Adam Szita
Assignee: Adam Szita
{{HiveMetaStoreClient.dropDatabase}} has a strange implementation to ensure
dealing with client side hooks (for non-native tables e.g. HBase). Currently it
starts by retrieving all the tables from HMS, and then sends {{dropTable}}
calls to HMS table-by-table. At the end a {{dropDatabase}} just to be sure :)
I believe this could be refactored so that it speeds up the dropDB in
situations where the average table count per DB is very high.
