Rui Li commented on FLINK-23857:
--------------------------------
OK, I tried with an empty source table w/o the {{1 != 1}} filter, and hive
doesn't clear the partition data in that case. Maybe there's some inconsistency
in hive. I guess it's more intuitive to clear the data since user intends to do
{{OVERWRITE}}. And therefore I prefer not to make a difference on this between
hive and default dialect.
