-------------------------------
Summary: Remove AggregateExpression1 and Aggregate Operator used
to evaluate AggregateExpression1s
Key: SPARK-9830
URL: https://issues.apache.org/jira/browse/SPARK-9830
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Yin Huai
Assignee: Yin Huai
Priority: Blocker
In 1.6.0, we should remove the old aggregation code path (used to evaluate
AggregateExpression1). While removing this code path, there are several code
clean up we need to do,
1. Remove all of our hacks from ResolveFunctions.
2. Remove all of the conversion logics from
{org.apache.spark.sql.catalyst.expressions.aggregate.utils}}.
3. Remove {{newAggregation}} field from {{logical.Aggregate}}.
4. Remove the query planning rule for old aggregate path.
