Add cleanup stages for UDFs
---------------------------
Key: HIVE-2261
URL: https://issues.apache.org/jira/browse/HIVE-2261
Project: Hive
Issue Type: Wish
Components: Query Processor
Reporter: Navis
Priority: Trivial
In some cases, we bind values at last stage of big SQL from other sources,
especially from memcached. I made that kind of UDFs for internal-use.
I found 'initialize' method of GenericUDF class is good place for making
connections to memcached cluster, but failed to find somewhere to
close/cleanup the connections. If there is cleaup method in GenericUDF class,
things can be more neat. If initializing entity like map/reduce/fetch could be
also providable to life-cycles(init/close), that makes perfect.
