Steve Loughran resolved HADOOP-16382.
-------------------------------------
Resolution: Won't Fix
we just don't get enough information back. Be nice if an http response header
always included clock time, but, well...
> Clock skew can cause S3Guard to think object metadata is out of date

> Key: HADOOP-16382
> URL: https://issues.apache.org/jira/browse/HADOOP-16382
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Priority: Minor
>
> When a S3Guard entry is added for an object, its last updated flag is taken
> from the local clock: if a getFileStatus is made immediately afterwards, the
> timestamp of the file from the HEAD may be > than the local time, so the DDB
> entry updated.
> This is even if the clocks are *close*. When updating an entry from S3, the
> actual timestamp of the file should be used to fix it, not local clocks
