MapReduce LearningMAP ": The main node reads input data, divides it into small chunks that can be solved in the same way (here is a divide-and-conquer idea), and distributes these small chunks to different working nodes (Worder nodes), each working node (worder node) Loop to do the same thing, this is going to be a tree-row structure (many of the models in distributed computing are related to graph theory, PageRank is also), and each leaf node has to

DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data s

parallelism, which means that they support very large datasets. The infrastructure layer of pig contains the compiler that generates the Map-reduce task. The language layer of Pig currently contains a native language--pig Latin, which was originally developed to be easy to program and ensure scalability. Pig is a sql-like language, a high-level query language built on MapReduce, which compiles some operations into the map and reduce of the MapReduce model, and the user can define their own func

In general, the main purpose of a multimode database is to meet operational requirements with high performance requirements and targeted data warehousing capabilities, rather than data mining scenarios like big

, it's obvious that the Hadoop cluster is dead. So obviously the hadoop1.x is flawed. If the is flawed, how can we make up for it? If it is still in the original frame to modify, get two jobtracker whether it is possible. This is certainly a scheme. But Hadoop is ambitious, too. As the first pioneer of big data, spar

Access to big data has been used for Hadoop for several years. Compared with the ever-changing front-end technology, I still prefer big data-this has been stir for many years, but also believe that the technology research in big
