Assignee: Rajesh Balamohan
> S3a: Consider reducing the number of connection aborts by setting correct
> length in s3 request

> Key: HADOOP-13203
> URL: https://issues.apache.org/jira/browse/HADOOP-13203
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Rajesh Balamohan

> Priority: Minor
> Attachments: HADOOP-13203-branch-2-001.patch

> Currently file's "contentLength" is set as the "requestedStreamLen", when
> invoking S3AInputStream::reopen(). As a part of lazySeek(), sometimes the
> stream had to be closed and reopened. But lots of times the stream was closed
> with abort() causing the internal http connection to be unusable. This incurs
> lots of connection establishment cost in some jobs. It would be good to set
> the correct value for the stream length to avoid connection aborts.
> I will post the patch once aws tests passes in my machine.
