When a reduce worker is notified by the master about these locations, it uses remote procedure calls to read the buffered data from the local disks of the map workers. When a reduce worker has read all intermediate data, it sorts it by the intermediate keys such that all occurrences of the same key are grouped together. If the amount of intermediate data is too large to fit in memory, an external sort is used. The reduce worker iterates over the sorted intermediate data and, for each unique intermediate key encountered, passes the key and the corresponding set of intermediate values to the user s reduce function. The output of the reduce function is appended to a final output file for this reduce partition. When all map tasks and reduce tasks have been completed, the master wakes up the user program. At this point, the MapReduce call in the user program returns back to the user code.

According to published interviews with Google IT managers, in each cluster s first year, it s typical that 1,000 individual machine failures will occur; thousands of hard drive failures will occur; one power distribution unit will fail, bringing down 500 to 1,000 machines for about 6 hours; 20 racks will fail, each time causing 40 to 80 machines to vanish from the network; 5 racks will go wonky, with half their network packets missing in action; and the cluster will have to be rewired once, affecting 5 percent of the machines at any given moment over a 2-day span. Also, the cluster has about a 50 percent chance of overheating, taking down most of the servers in less than 5 minutes and taking 1 to 2 days to recover. With this kind of scale, reliability has to be built into the software, not the hardware. As you ve read, for this reason and to minimize hardware costs, Google opts to go with bare-bones commodity hardware and not high-end, supposedly bullet-proof machines. You can better appreciate MapReduce by looking briefly at the handful of examples in table 6.2. It s been effectively employed by the largest web companies on the planet, such as Google and Yahoo!.

Table 6.2 Examples where MapReduce is used in high-scale production applications How MapReduce is employed The map function emits a line if it matches a given pattern. The reduce function is an identity function that copies the supplied intermediate data to the output. The map function outputs <target, source> pairs for each link to a target URL found in a page named source. The reduce function concatenates the list of all source URLs associated with a given target URL and emits the pair <target, list(source)>.

Examples where MapReduce is used in high-scale production applications (continued ) How MapReduce is employed A term vector summarizes the most important words that occur in a document or a set of documents as a list of <word, frequency> pairs. The map function emits a <hostname, term vector> pair for each input document (where the hostname is extracted from the URL of the document). It passes the reduce function all per-document term vectors for a given host. It adds together these term vectors, throwing away infrequent terms, and then emits a final <hostname, term vector> pair. The map function parses each document and emits a sequence of <word, document ID> pairs. The reduce function accepts all pairs for a given word, sorts the corresponding document IDs, and emits a <word, list(document ID)> pair. The set of all output pairs forms a simple inverted index. It s easy to augment this computation to keep track of word positions.
