--------------------------------------
Summary: Implement `doCanonicalize` for BatchScanExec
Key: SPARK-27580
URL: https://issues.apache.org/jira/browse/SPARK-27580
Project: Spark
Issue Type: Task
Components: SQL
Affects Versions: 3.0.0
Reporter: Gengliang Wang
The method `QueryPlan.sameResult` is used for comparing logical plans in order
to:
1. cache data in CacheManager
2. uncache data in CacheManager
3. Reuse subqueries
4. etc...
Currently the method `sameReuslt` always return false for `BatchScanExec`. We
should fix it by implementing `doCanonicalize` for the node.
