    • Type: Bug
    • Status: Closed
    • Priority: Major
    • Resolution: Fixed
    • Affects Version/s: 0.20.205.0
    • Fix Version/s: 2.0.0-alpha

      Ubuntu, hadoop cloudera CDH3U2, Oracle SUN JDK 6U30

      Description

      LineReader reader = new LineReader(in, 4096);
      ...

      Text text = new Text();
      while((reader.readLine(text)) > 0) {
      ...
      text.clear();
      }
      }

      Even the clear() method is called each time, some bytes are still not filled as zero.
      So, when reader.readLine(text) is called in a loop, some bytes are dirty which was from last call.
