Examples of DeprecatedUTF8

org.apache.hadoop.hdfs.DeprecatedUTF8
A simple wrapper around {@link org.apache.hadoop.io.UTF8}. This class should be used only when it is absolutely necessary to use {@link org.apache.hadoop.io.UTF8}. The only difference is that using this class does not require "@SuppressWarning" annotation to avoid javac warning. Instead the deprecation is implied in the class name. This should be treated as package private class to HDFS.
