> -------------------------------------------------------------------------
>
> Key: HADOOP-18378
> URL: https://issues.apache.org/jira/browse/HADOOP-18378
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Ahmar Suhail
> Assignee: Alessandro Passaro
> Priority: Minor
> Labels: pull-request-available
>
> Implement readFully(long position, byte[] buffer, int offset, int length) in
> PrefetchingInputStream, as it currently uses FSInputStream's
> [readFully|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FSInputStream.java#L136]
> which calls read(long position, byte[] buffer, int offset, int length).
> This read then seeks to the position (which is ok), but then seeks back to
> the original starting position at the end (so always seeking back to 0). this
> is pretty bad for the prefetching implementation as it means lots of caching
> to disk and getting blocks from disk.
