Uses of Closeable in org.apache.hadoop.examples
 

Classes in org.apache.hadoop.examples that implement Closeable
 class RandomWriter
          This program uses map/reduce to just run a distributed job where there is no interaction between the tasks and each task write a large unsorted random binary sequence file of BytesWritable.
static class RandomWriter.Map
           
static class WordCount.MapClass
          Counts the words in each line.
static class WordCount.Reduce
          A reducer class that just emits the sum of the input values.
 

Uses of Closeable in org.apache.hadoop.mapred
 

Subinterfaces of Closeable in org.apache.hadoop.mapred
