Subject [jira] [Created] (HADOOP-7940) method clear() in org.apache.hadoop.io.Text does not work
Date Sat, 24 Dec 2011 14:50:30 GMT
method clear() in org.apache.hadoop.io.Text does not work
---------------------------------------------------------

                 Key: HADOOP-7940
                 URL: https://issues.apache.org/jira/browse/HADOOP-7940
             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,


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.
