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.
