Cheng Su created SPARK-32986:
--------------------------------

             Summary: Add bucket scan info in explain output of FileSourceScanExec
                 Key: SPARK-32986
                 URL: https://issues.apache.org/jira/browse/SPARK-32986
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.1.0
            Reporter: Cheng Su


As a followup from discussion in [https://github.com/apache/spark/pull/29804#discussion_r493229395] , currently for `FileSourceScanExec` explain output, there's no information to indicate whether the table is read as bucketed table. And if not read as bucketed table, what's the reason behind it. Add this info into `FileSourceScanExec` explain output, can help users/developers understand query plan more easily without spending a lot of time debugging why table is not read as bucketed table.
