[jira] [Created] (HADOOP-18283) Review s3a prefetching input stream retry code

Steve Loughran created HADOOP-18283:
---------------------------------------

             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
