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.
