---------------------------------------
Summary: Review s3a prefetching input stream retry code
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
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
