-----------------------------------
kevinwilfong has commented on the revision "HIVE-2870 [jira] Throw an error
when a nonexistent partition is accessed in strict mode".
That conf var is currently being used to throw an error if a query is written
to create dynamic partitions and it doesn't produce any partitions. That is a
weird dependency to introduce, I think it would be better to create a new
variable.
Could you print an warning or at least log one if strict mode is set to false
and a partition is empty. This would be useful because users could still see
that they are querying a partition unnecessarily, but without the risk of
breaking existing queries.

> 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.
