[jira] [Created] (HIVE-2312) Make CLI variables available to UDFs

Make CLI variables available to UDFs
------------------------------------

                 Key: HIVE-2312
                 URL: https://issues.apache.org/jira/browse/HIVE-2312
             Project: Hive
          Issue Type: Improvement
          Components: CLI, Clients, UDF
            Reporter: Adam Kramer


Straightforward use case: My UDFs should be able to condition on whether hive.mapred.mode=strict or nonstrict.

But these things could also be useful for certain optimizations. For example, a UDAF knowing that there is only one reduce phase could avoid a lot of pushing data around unnecessarily.
