    Moving to Hadoop 0.90 [HADOOP-9623](https://issues.apache.org/jira/browse/HADOOP-9623) was what could be described as "an accidental disaster"'; the patch swallowed exceptions "which should never happen", resulting in [HADOOP-10589](https://issues.apache.org/jira/browse/HADOOP-10589); a seek(0) on a 0-byte file NPE-ing. (trivia: It was fixed by probably the only piece of co-recursive code in core hadoop)
    
    One issue with 0.90 is that the `close()` call on an input stream reads _all remaining bytes on the resource_ [HADOOP-12376](https://issues.apache.org/jira/browse/HADOOP-12376). This hurts: moving up to 0.94 may fix it. From the hadoop core perspective, the move to 0.90 broke enough things that we are scared to go near the s3n code again; all future work is in s3a.
    
    To summarise then: this may break s3n if not shaded, but you should be encouraging people to use s3a on Hadoop 2.7+ anyway
