> Project: Hadoop Common
> Issue Type: Bug
> Components: io
> Affects Versions: 0.20.205.0
> Environment: Ubuntu, hadoop cloudera CDH3U2, Oracle SUN JDK 6U30
> Reporter: Aaron,
> Assignee: Csaba Miklos
> Labels: patch
> Fix For: 0.24.0, 0.23.3

> 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.
