Hadoop is considered to be a mapreduce running on HDFS (Distributed File System). 　　Increased number of potential applications through Yarn,hadoop 2.0. Hadoop has always been a general term for all kinds of open source innovations that are more or less integrated into the unified large data architecture. 　　Some people believe that the core of Hadoop is a distributed File System (HDFS), while a series of alternative HDFS databases such as HBase and Cassandra are shaking the claim. Hadoop used to have a special job ...

Next, Wang Shupeng, associate researcher of Institute of Information Engineering, Chinese Academy of Sciences, shared the development and use of new NoSQL large data management systems (BDMS). Wang Shupeng said most of the projects he contacted were non-Internet applications, such as security and transportation. 　　These industries are now faced with big data, but many popular NoSQL databases do not apply to them, so they independently developed a NoSQL database management system. The design of the target system is highly scalable: it can be achieved by increasing the linear branch of the node ...
