Varje segment bearbetas parallellt 2020-07-06 In this phase the reduce(Object, Iterable, org.apache.hadoop.mapreduce.Reducer.Context) method is called for each in the sorted inputs. The output of the reduce task is typically written to a RecordWriter via TaskInputOutputContext.write(Object, Object). The output of the Reducer is not re-sorted. Example: 2021-04-22 The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models.
