John Sichi commented on HIVE-2261: ---------------------------------- I think we should put in some of the common base class changes from HIVE-1016 before implementing this. > 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. -- This message is automatically generated by JIRA.
