> SocketException with S3 native file system causes job to fail
> -------------------------------------------------------------
>
> Key: HADOOP-4013
> URL: https://issues.apache.org/jira/browse/HADOOP-4013
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/s3
> Affects Versions: 0.18.0
> Reporter: Karl Anderson
>
> I'm running Hadoop 0.18.0 with a Amazon S3 native filesystem input (s3n URL
> given for input on the commandline). I'm having mapper tasks die, which is
> killing the job. The error is "java.net.SocketException: Connection reset".
> I'm using streaming, but my code isn't using any S3 classes itself, this is
> being done for me by the input reader. Traceback from the task details, and
> my invocation, are appended.
> Several mapper tasks complete before this happens, and I've had other jobs
> work with input from smaller Amazon S3 buckets for the same account. So this
> looks like a connectivity issue, where the input reader should realize that
> it's calling a web service and try again.
> Traceback:
