----------------------------------
Summary: Analyzer should be able run on top of optimized rule
Key: SPARK-17482
URL: https://issues.apache.org/jira/browse/SPARK-17482
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Davies Liu
Right now, analyzer has some assumption that the query came from parser or
DataFrame operations (or analyzed), optimizer may break these assumption. It
may process wrong answer if ran analyzer on a optimized logical plan.
In long term, the analyzer rules should not have these assumption, it should
still produce correct result whenever it's optimized or not. We should have
unit test to ensure that.
This may depends on how large the change needed to meet this requirement.
