pvargacl opened a new pull request #1779:
URL: https://github.com/apache/hive/pull/1779
### What changes were proposed in this pull request?
- 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.
### Why are the changes needed?
- performance improvement
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
