org.apache.hadoop.mapred.RecordReader

Packages that use RecordReader
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.mapred.join Given a set of sorted datasets keyed with the same class and yielding equal partitions, it is possible to effect a join of those datasets prior to the map. 
org.apache.hadoop.mapred.lib Library of generally useful mappers, reducers, and partitioners. 
org.apache.hadoop.streaming Hadoop Streaming is a utility which allows users to create and run Map-Reduce jobs with any executables (e.g.
