> S3AInputStream read does not re-open the input stream on the second read 
> retry attempt

>                 URL: https://issues.apache.org/jira/browse/HADOOP-17764
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs/s3
>    Affects Versions: 3.3.1
>            Reporter: Zamil Majdy
>            Priority: Major
>              Labels: pull-request-available
>          Time Spent: 1.5h
>  Remaining Estimate: 0h
>
> *Bug description:*
> The read method in S3AInputStream has this following behaviour when an 
> IOException happening during the read:
>  * {{reopen and read quickly}}: The client after failing in the first attempt 
> of {{read}}, will reopen the stream and try reading again without {{sleep}}.
>  * {{reopen and wait for fixed duration}}: The client after failing in the 
> attempt of {{read}}, will reopen the stream, sleep for 
> {{fs.s3a.retry.interval}} milliseconds (defaults to 500 ms), and then try 
> reading from the stream.
> While doing the {{reopen and read quickly}} process, the subsequent read will 
> be retried without reopening the input stream in case of the second failure 
> happened. This leads to some of the bytes read being skipped which results to 
> corrupt/less data than required. 
>  
> *Scenario to reproduce:*
>  * Execute S3AInputStream `read()` or `read(b, off, len)`.
>  * The read failed and throws `Connection Reset` exception after reading some 
> data.
>  * The InputStream is re-opened and another `read()` or `read(b, off, len)` 
> is executed
>  * The read failed for the second time and throws `Connection Reset` 
> exception after reading some data.
>  * The InputStream is not re-opened and another `read()` or `read(b, off, 
> len)` is executed after sleep
>  * The read succeed, but it skips the first few bytes that has already been 
> read on the second failure.
>  
> *Proposed fix:*
> [https://github.com/apache/hadoop/pull/3109]
> Added the test that reproduces the issue along with the fix
