> 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.
