Thanks [~spoganshev] for the work here.
Hi [~stevel@apache.org], in order to get HADOOP-17338 to 2.10 branch, I think it'd help to get this one in beforehand, I tested out both this one and HADOOP-17338 on hadoop-2.10 branch, and put the test result in [https://github.com/apache/hadoop/pull/2685|https://github.com/apache/hadoop/pull/2685,] , would you please help review? thanks a lot.

> Since only {{IOException}} is getting caught in [closeStream|https://github.com/apache/hadoop/blob/24080666e5e2214d4a362c889cd9aa617be5de81/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/S3AInputStream.java#L579], {{reopen()}} fails in case {{SdkClientException}} occurs on a drain attempt. This leads to multiple failing retries of {{invoker.retry("read",...)}} and then the whole {{read()}} operation failing.
