------------------------------------------
Summary: Hive generates a add partition event with empty partition
list
Key: HIVE-22100
URL: https://issues.apache.org/jira/browse/HIVE-22100
Project: Hive
Issue Type: Bug
Reporter: Vihang Karajgaonkar
If the user issues a {{alter table <table> add if not exists partition
<partition_spec>}} and it the partition already exists, no partition is added.
However, metastore still generates a {{ADD_PARTITION}} event with empty
partition list. An {{alter table <table> drop if exists partition
<partition_spec>}} does not generate the {{DROP_PARTITION}} event in case the
partition is not existing.
This behavior is inconsistent and misleading. Metastore should not generate
such add_partition events.
