hudi-bot opened a new issue, #15114: URL: https://github.com/apache/hudi/issues/15114
After rebasing Hudi's COW table onto `BaseFileOnlyRelation` from `HadoopFsRelation`, we lost very helpful file-scanning metrics like # of files scanned, total size of files scanned, etc. After some investigation, i've found out that this occurred b/c now instead of relying on `FileScan` node in Spark plans like we're before, it now uses `DataScan` node that doesn't provide such metrics. This unwanted transition occurred b/c Spark internally predicates on `HadoopFsRelation` to decide whether it's a `FileScan` or `DataScan`, and since we stopped using `HadoopFsRelation` Hudi relations now fall into the latter bucket ## JIRA info - Link: https://issues.apache.org/jira/browse/HUDI-3882 - Type: Improvement - Epic: https://issues.apache.org/jira/browse/HUDI-1297 -- This is an automated message from the Apache Git Service.
