Edward Capriolo commented on HIVE-7025:
---------------------------------------

I like this. I coded something like this by hand at my last job. I did run into issue where tables with huge number of partitions caused memory issues and had to page / limit the number of objects I would access in one go.

Anyway your test case does not include a partitioned table. I am assuming the reinvention is set on the table but you are using the create time of the partition? It might be good to include that in your unit test.
