org.apache.hadoop.hdfs.DeprecatedUTF8

All Implemented Interfaces:

Comparable<UTF8>, Writable, WritableComparable<UTF8>

@InterfaceAudience.Private
public class DeprecatedUTF8
extends UTF8

A simple wrapper around UTF8. This class should be used only when it is absolutely necessary to use 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.
