Description

When a table does not exist and someone tries to read from it in a query, Hive throws an error.

But if a partition is directly accessed that does not exist, an error is not thrown. This is inconsistent and also leads to a lot of confused users who get no output.

This task is to cause Hive to throw an error when the partition pruner for a query eliminates ALL existing partitions for some table when running in strict mode.
