Examples of org.apache.hadoop.mapreduce.TaskInputOutputContext

org.apache.hadoop.mapreduce.TaskInputOutputContext
A context object that allows input and output from the task. It is only supplied to the {@link Mapper} or {@link Reducer}. @param < KEYIN> the input key type for the task @param < VALUEIN> the input value type for the task @param < KEYOUT> the output key type for the task @param < VALUEOUT> the output value type for the task
