      Description

      the following seed fails reliably for me on master...

      git bisect says this is the first commit where it started failing..

      ddc65d977f920013c5fca16c8ac75ae2c6895f9d is the first bad commit

          LUCENE-6932: RAMInputStream now throws EOFException if you seek beyond the end of the file
          
          git-svn-id: https://svn.apache.org/repos/asf/lucene/dev/trunk@1726039 13f79535-47bb-0310-9956-ffa450edef68
      
      

      ...which seems remarkable relevant and likely to indicate a problem that needs fixed in the HdfsDirectory code (or perhaps just the test)
