Steve Loughran updated HADOOP-16202:
------------------------------------
Summary: S3A openFile() operation to support explicit length parameter

parameters)
> S3A openFile() operation to support explicit length parameter
> -------------------------------------------------------------
>
> Key: HADOOP-16202
> URL: https://issues.apache.org/jira/browse/HADOOP-16202
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
>
> The {{openFile()}} builder API lets us add new options when reading a file
> Proposed: allowing applications to explicitly demand on. If we explicitly add
> the values in the S3A filestatus & located filestatus (maybe even:
> checksum?), then you can list a directory and. knowing those values,
> explicitly ask for that version of file.
> {code}
> org.apache.fs.s3a.open.versionid + versionID
> org.apache.fs.s3a.open.etag + etag
> {code}
> setting both will be an error.
