Steve Loughran commented on HADOOP-13203:
-----------------------------------------
thanks...given the precommit went through I'll take the +1 as confirmed, run
another test against the patch rebased onto branch 2
regarding the failure, it is in the serialzied set; HADOOP-13271 looks at it.
I think it's a delayed delete visibility issue, or similar; the test is in
hadoop-common so might need some working to isolate and handle
consistency...probably initially pull it out into its own. The fact that it
doesn't fail standalone makes it hard though.

> 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.
