Work Description: steveloughran commented on PR #4386:
URL: https://github.com/apache/hadoop/pull/4386#issuecomment-1151029766
made some comments. looked at the EOF swallowing code...i think we need to
be happy there that all is good in terms of handling recoverable failures but
not retrying on nonrecoverable ones.

> The following tests are failing when prefetching is enabled:
> testRandomIORandomPolicy - expects stream to be opened 4 times (once for
> every random read), but prefetching will only open twice.
> testDecompressionSequential128K - expects stream to be opened once, but
> prefetching will open once for each block the file has. landsat file used in
> the test has size 42MB, prefetching block size = 8MB, expected open count is
> 6.
> testReadWithNormalPolicy - same as above.
> testRandomIONormalPolicy - executes random IO, but with a normal policy.
> S3AInputStream will abort the stream and change the policy, prefetching
> handles random IO by caching blocks so doesn't do any of that.
> testRandomReadOverBuffer - multiple assertions failing here, also depends a
> lot on readAhead values, not very relevant for prefetching
