Summary: Reduce FS creation in Warehouse::getDnsPath for object

Key: HIVE-24838
URL: https://issues.apache.org/jira/browse/HIVE-24838
Project: Hive
Issue Type: Improvement

Warehouse::getDnsPath gets invoked from multiple places (e.g getDatabase()
etc). In certain cases like dynamic partition loads, lot of calls FS
instantiation calls can be avoided for object stores.
It would be good to check for BlobStorages and if so, it should be possible to
avoid FS creation.
