Google created a mapreduce,mapreduce cluster in 2004 that could include thousands of parallel-operation computers. At the same time, MapReduce allows programmers to quickly transform data and execute data in such a large cluster. From MapReduce to Hadoop, this has undergone an interesting shift. MapReduce was originally a huge amount of data that helped search engine companies respond to the creation of indexes created by the World Wide Web. Google initially recruited some Silicon Valley elites and hired a large number of engineers to ...

October may be the one months worth noting in the history of large data. Because in this month, we can redefine Hadoop. It can be a research framework of large data batch processing, and it can also be a high speed engine and interactive analysis product of structured and unstructured data large-scale parallel analysis data. > already have companies trying to prove it. Recently, the industry held a special meeting to promote Hadoop itself Hadoop-plus-sql architecture, add advanced analysis function, through the image display and so on. Among them, three ...

We know that enterprise-class business intelligence products include Oracle Hyperion, SAP BusinessObjects, and IBM Cogonos, while Agile products have qlikview, tableau, and Tibco Spotfire. If it turns out that big data has to buy enterprise-class products, that means big data can cost a lot. But this is not absolute, by using large data agile technology, each ...

The Apache Haddo is a batch computing engine that is the open source software framework for large data cores.
