Hi,
When using spark.sql() to perform alter table operations I found that spark changes the table owner property to the execution user. Then I digged into the source code and found that in HiveClientImpl, the alterTable function will set the owner of table to the current execution user. Besides, some other operations like alter partition, getPartitionOption and so on do the same. Can some experts explain why should we do this? What if just behave like hive which does not change the owner when doing these kind of operations?
