---------------------------------------
Summary: S3A create(path, overwrite=true) need only check for path
being a dir, not a file
Key: HADOOP-13950
URL: https://issues.apache.org/jira/browse/HADOOP-13950
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 2.7.3
Reporter: Steve Loughran
Priority: Minor
When you create a file with overwrite=true, you don't care that a path resolves
to a file, only that there isn't a directory at the destination.
S3A can use this, bypass the {{GET path}} and only do a {{GET path + "/"}} and
LIST path. That way: one HTTPS request saved, and no negative caching of the
path to confuse followup checks.
That is: better performance and consistency
