------------------------------------
Summary: Change an FS#exists call to FS#isFile call in AcidUtils
Key: HIVE-23608
URL: https://issues.apache.org/jira/browse/HIVE-23608
Project: Hive
Issue Type: Improvement
Reporter: Karen Coppage
Assignee: Karen Coppage
Currently S3AFileSystem#isFile and S3AFileSystem#exists have the same
implementation. HADOOP-13230 will optimize S3AFileSystem#isFile by only doing a
HEAD request for the file; no need for a LIST probe for a directory (isDir will
do that). S3AFileSystem#exists will still need both.
This and HIVE-23533 will get rid of the last exists() calls in AcidUtils.
