convert commonly used udfs to generic udfs
------------------------------------------
Key: HIVE-1638
URL: https://issues.apache.org/jira/browse/HIVE-1638
Project: Hadoop Hive
Issue Type: Improvement
Components: Query Processor
Reporter: Namit Jain
Assignee: Siying Dong
Copying a mail from Joy:
i did a little bit of profiling of a simple hive group by query today. i was
surprised to see that one of the most expensive functions were in converting
the equals udf (i had some simple string filters) to generic udfs.
(primitiveobjectinspectorconverter.textconverter)
am i correct in thinking that the fix is to simply port some of the most
popular udfs (string equality/comparison etc.) to generic udsf?
