> 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.
