[jira] [Created] (SPARK-27580) Implement `doCanonicalize` for BatchScanExec

Gengliang Wang created SPARK-27580:
--------------------------------------

             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.
