@viirya @yuananf a quick check of recent spark releases shows this fix is
not in. Any suggested workarounds in the meantime for dynamic partition insert
overwrites?
It sounds like if the user does the logic of deleting the necessary
partitions before running the dynamic insert overwrite query then hive will go
down the "happy" performant path. This will require calculating the dynamic
partitions before running the insert query, but if you can do that then this
workaround will work right?
