Ted Yu commented on HADOOP-6868:
--------------------------------
So the correct call in the above use case should be:
String valueString = new String(valueText.getBytes(), 0, valueText.getLength(),
"UTF-8");
Text class Java doc should document explicitly about this use case.
> Text class should provide method to return byte array of getLength()

> URL: https://issues.apache.org/jira/browse/HADOOP-6868
> Project: Hadoop Common
> Issue Type: Bug
> Components: util
> Affects Versions: 0.20.2
> Reporter: Ted Yu
>
> People would use the following code to convert Text to String:
> String valueString = new String(valueText.getBytes(), "UTF-8");
> However, if Text is reused, the above call would return String of
> monotonically increasing length.
> From 'Hadoop and XML' discussion thread:
> The problem I am seeing is between the Map phase and the
> Reduce phase, the XML is getting munged. For Example:
> </PrivateRate>
> </PrivateRateSet>te>
> Text should provide method to return byte array of getLength() length.
