> S3A: fs.s3a.connection.expect.continue controls 100 CONTINUE behavior

>                 URL: https://issues.apache.org/jira/browse/HADOOP-19317
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/s3
>    Affects Versions: 3.4.1
>            Reporter: Steve Loughran
>            Assignee: Steve Loughran
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 3.5.0, 3.4.2
>
>
> New option
> {code}
>   fs.s3a.connection.expect.continue
> {code}
> This controls whether or not an PUT request to the S3 store
> sets the "Expect: 100-continue" header and awaits a 100 CONTINUE
> response before uploading any data.
> This allows for throttling and other problems to be detected fast.
> The default is "true" -the header is sent.
> It seems like either the AWS SDK or http client libraries underneath don't 
> recognise a dead HTTPS connection when using this.
> Leaving as enabled as it can cope with heavy load better (clients can get a 
> 503 and know to back off before uploading any data.
