> S3AInputStream: Handle http stream skip(n) skipping < n bytes in a forward
> seek
> -------------------------------------------------------------------------------
>
> Key: HADOOP-14606
> URL: https://issues.apache.org/jira/browse/HADOOP-14606
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.8.1
> Reporter: Steve Loughran
> Priority: Critical
>
> There's some hints in the InputStream docs that {{skip(n)}} may skip <n
> bytes. Codepaths only seem to do this if read() returns -1, meaning end of
> stream is reached.
> If that happens when doing a forward seek via skip, then we have got our
> numbers wrong and are in trouble. Look for a negative response, log @ ERROR
> and revert to a close/reopen seek to an absolute position.
> *I have no evidence of this acutally occurring*
