Then MapReduce shuffles the map output by key and does another parallel computation on the redistributed map output, writing the results to the file system in the Reduce phase of the computation.

然后MapReduce按照各个键改组映射输出，对重新分配的映射输出执行另一项并行计算，在计算的归纳阶段将结果写入到文件系统中。

A key selling point for MapReduce is its ability to abstract the operational parallelization semantics - how parallel programming works - away from the developer.

MapReduce的关键特点是它能够对开发人员隐藏操作并行语义—并行编程的具体工作方式。

In the initial example above, the key data was user profiles, which could be distributed (partitioned) across a set of machines for parallel processing.

在上例中，关键数据是用户配置文件，可以跨一组机器分布(分区)以进行并行处理。

In addition to clearing our last remaining scientific hurdle, we need to advance a parallel engineering agenda into key reactor technologies that will enable commercial fusion power plants to reliably deliver electricity in a highly competitive market.

For me, the potential parallel -- and the key challenge facing Governor Bush -- is how the vice-president's campaign dealt with the gubernatorial challenger.

The Sebago case involves one of the key arguments made by parallel importers, that trademark owners who sell their goods in Europe must be taken to have consented to the sale of other goods that are essentially the same.
