-------------------------------
Summary: Support CombineSum in Code Gen
Key: SPARK-6451
URL: https://issues.apache.org/jira/browse/SPARK-6451
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Yin Huai
Priority: Blocker
Since we are using CombineSum at the reducer side for the SUM function, we need
to make it work in code gen. Otherwise, code gen will not convert Aggregates
with a SUM function to GeneratedAggregates (the code gen version).
