Steve Loughran commented on HADOOP-16490:
-----------------------------------------
This now contains HADOOP-13884; no more checks for HEAD path in create(path,
overwrite=true). We don't care
> S3GuardExistsRetryPolicy handle FNFE eventual consistency better

> Key: HADOOP-16490
> URL: https://issues.apache.org/jira/browse/HADOOP-16490
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
>
> If S3Guard is encountering delayed consistency (FNFE from tombstone; failure
> to open file) then
> * it only retries with the same times as everything else. We should make it
> differently configurable
> * when an FNFE is finally thrown, rename() treats it as being caused by the
> original source path missing, when in fact its something else. Proposed:
> somehow propagate the failure up differently, probably in the
> S3AFileSystem.copyFile() code
