---------------------------------------

             Summary: Reduce number of FS getFileStatus calls in AcidUtils::getHdfsDirSnapshots
                 Key: HIVE-22609
                 URL: https://issues.apache.org/jira/browse/HIVE-22609
             Project: Hive
          Issue Type: Bug
            Reporter: Rajesh Balamohan


[https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/io/AcidUtils.java#L1380]

ACID delta folder contains {{_orc_acid_version}} and {{bucket_00000}} files. For both these files, parent dir is the same. Number of getFileStatus in such cases should be reduced by 1/2.
