Bharathkrishna Guruvayoor Murali updated IMPALA-8338:
-----------------------------------------------------
Description:
HIVE-21077 adds CREATION_TIME to Database, and it will be available in the
metastore notifications. Hence,
# For CREATE_DATABASE events, we should compare the creationTime of the
Database in catalog with the Database in the event to make sure we are ignoring
the event only if catalog has the latest Database object.
# For DROP_DATABASE events, we should check that creation time of database in
the notification and the catalog match to make sure that we are removing the
correct database object.
