[jira] [Updated] (HIVE-2870) Throw an error when a nonexistent
partition is accessed in strict mode

Reviewers: JIRA
HIVE-2870: Throw an error when a nonexistent partition is accessed.
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 patch 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.
