Michael Armbrust commented on SPARK-6451:
-----------------------------------------
I went ahead and reverted the root cause from branch-1.3 as changes to code gen
are a little scare to put in a maintenance branch. We can still try and get
the fix into master.
> 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
> Assignee: Michael Armbrust
> 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).
