------------------------------------
Summary: Remove unnecessary FileSystem#exists calls from ql module
Key: HIVE-23492
URL: https://issues.apache.org/jira/browse/HIVE-23492
Project: Hive
Issue Type: Improvement
Reporter: Karen Coppage
Assignee: Karen Coppage
Wherever there is an exists() call before open() or delete(), remove it and
infer from the FileNotFoundException raised in open/delete that the file does
not exist. Exists() just checks for a FileNotFoundException so it's a waste of
time, especially on clunkier FSes
