Change subject: IMPALA-8847: Ignore add partition events with empty partition list ...................................................................... IMPALA-8847: Ignore add partition events with empty partition list Certain Hive queries like "alter table <table> add if not exists partition (<part_spec>)" generate a add_partition event even if the partition did not really exists. Such events have a empty partition list in the event message which trips on the Precondition check in the AddPartitionEvent. This causes event processor to go into error state. The only way to recover is to issue invalidate metadata in such a case. The patch adds logic to ignore such events. Testing: 1. Added a test case which reproduces the issue. The test case works after the patch is applied.
