--------------------------------
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.
