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.
