Status: Patch Available (was: Open)
> Change an FS#exists call to FS#isFile call in AcidUtils
> -------------------------------------------------------

> Key: HIVE-23608

>
> 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.
