Data Types: char | string Display— Toggle for command line progress output 'on' (default) | 'off' Toggle for command line progress output, specified as 'on' or 'off'. The default is 'on', so that mapreduce displays progress information in the command window during the map and reduce ...
The MapReduce framework operates on <key, value> pairs, that is, the framework views the input to the job as a set of <key, value> pairs and produces a set of <key, value> pairs as the output of the job, conceivably of different types. ...
Specifies the Combiner class of a MapReduce job. The Combiner class is empty by default. You can also configuremapreduce.job.combine.classinmapred-site.xml. The Combiner class can be used only when the input and output key and value types of the reduce task are the same. setInputFormatCla...
and a reduce function that merges all intermediate values associated with the same intermediate key. Many real world tasks are expressible in this model, as shown in the paper. MapReduce是一个关于实施大型数据集处理和生成的编程模型。 用户指定一个用于处理k/v对并生成中间态k/v对集合的映射(map)...

The MapReduce framework operates on key-value pairs, that is, the framework views the input to the job as a set of key-value pairs and produces a set of key-value pair as the output of the job, conceivably of different types. The key and value classes have to be serializable by the...
Input and Output types of a MapReduce job: (input) <k1, v1> ->map-> <k2, v2> ->combine-> <k2, v2> ->reduce-> <k3, v3> Example: WordCount v1.0 Before we jump into the details, lets walk through an example MapReduce application to get a flavour for how they work. ...
