Zhaojing Yu updated HUDI-3882:
------------------------------
Fix Version/s: 0.13.0
(was: 0.12.1)
> Make sure Hudi Spark relations implementations provide similar file-scanning
> metrics
> ------------------------------------------------------------------------------------
>
> Key: HUDI-3882
> URL: https://issues.apache.org/jira/browse/HUDI-3882
> Project: Apache Hudi
> Issue Type: Improvement
> Reporter: Alexey Kudinkin
> Assignee: Alexey Kudinkin
> Priority: Critical
> Fix For: 0.13.0
>
>
> 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
