org.apache.hadoop.io.RawComparator

Packages that use RawComparator
org.apache.hadoop.io Generic i/o code for use when reading and writing data to the network, to databases, and to files. 
org.apache.hadoop.io.serializer This package provides a mechanism for using different serialization frameworks in Hadoop. 
org.apache.hadoop.mapred A software framework for easily writing applications which process vast amounts of data (multi-terabyte data-sets) parallelly on large clusters (thousands of nodes) built of commodity hardware in a reliable, fault-tolerant manner. 
org.apache.hadoop.record Hadoop record I/O contains classes and a record description language translator for simplifying serialization and deserialization of records in a language-neutral manner.

Uses of RawComparator in org.apache.hadoop.io.serializer
 

Classes in org.apache.hadoop.io.serializer that implement RawComparator
 class DeserializerComparator<T>
           A RawComparator that uses a Deserializer to deserialize the objects to be compared so that the standard Comparator can be used to compare them.
 class JavaSerializationComparator<T extends Serializable & Comparable<T>>
           A RawComparator that uses a JavaSerialization Deserializer to deserialize objects that are then compared via their Comparable interfaces.
