URL: https://github.com/apache/hive/pull/854
 
 
   …ystem calls
   
   getAcidState() can make use of single recursive directory listing call and save a snapshot of the directory. Later this snapshot is used to probe existence of some files, such as _acid_version. This optimization was turned of in OrcInputFormat. Even after turning this on, isCompactedBase and isMetadataFile were not using the snapshot saved.

> Fix for HIVE-21225 is not enabled in query coordinator codepath. The last argument (generateDirSnapshots) for getAcidState() is set to false when invoked by callInternal(). Also, snapshot is not used for file exists calls.
