Peter Varga reassigned HIVE-24535:
----------------------------------
> Cleanup AcidUtils.Directory and remove unnecessary filesystem listings
> ----------------------------------------------------------------------
>
> Key: HIVE-24535
> URL: https://issues.apache.org/jira/browse/HIVE-24535
> Project: Hive
> Issue Type: Improvement
> Reporter: Peter Varga
> Assignee: Peter Varga
> Priority: Major
>
> * AcidUtils.getAcidState is doing a recursive listing on S3 FileSystem, it
> already knows the content of each delta and base directory, this could be
> returned to OrcInputFormat, to avoid listing each delta directory again there.
> * AcidUtils.getAcidstate submethods are collecting more and more infos about
> the state of the data directory. This could be done directly to the final
> Directory object to avoid 10+ parameters in methods.
> * AcidUtils.Directory, OrcInputFormat.AcidDirInfo and AcidUtils.TxnBase can
> be merged to one class, to clean up duplications.
