Prasanth Jayachandran commented on HIVE-9076:
---------------------------------------------
[~navis] Log file should tell what files are renamed, moved and merged. Would
it be possible to get the logs from OrcFileMergeOperator,
AbstractFileMergeOperator and MergeFileMapper?
> incompatFileSet in AbstractFileMergeOperator should be marked to skip task id
> check

> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Reporter: Navis
> Assignee: Navis
> Priority: Minor
>
> In some file composition, AbstractFileMergeOperator removes incompatible
> files. For example,
> {noformat}
> 000000_0 (v12)
> 000000_0_copy_1 (v12)
> 000000_1 (v11)
> 000000_1_copy_1 (v11)
> 000000_1_copy_2 (v11)
> 000000_2 (v12)
> {noformat}
> 000000_1 (v11) will be removed because 000000 is assigned to new merged file.
