> Review s3a prefetching input stream retry code; synchronization
> ---------------------------------------------------------------
>
> Key: HADOOP-18283
> URL: https://issues.apache.org/jira/browse/HADOOP-18283
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Steve Loughran
> Priority: Major
>
> Need to review S3A prefetching stream retry logic
> * no attempt to retry on unrecoverable errors
> * do try on recoverable ones
> * no wrap of retry by retry.
> * annotate classes with Retries annotations to aid the review.
> a key concern has to be that transient failure of prefetch is recovered
> from; things like deleted/shortened file fails properly on the next read call
