In fact, see the official Hadoop document has been able to easily configure the distributed framework to run the environment, but since the write a little bit more, at the same time there are some details to note that the fact that these details will let people grope for half a day. Hadoop can run stand-alone, but also can configure the cluster run, single run will not need to say more, just follow the demo running instructions directly to execute the command. The main point here is to talk about the process of running the cluster configuration. Environment 7 ordinary machines, operating systems are Linux. Memory and CPU will not say, anyway had ...

Pig is a Yahoo donated project to Apache and is currently in the Apache incubator, but the basic functionality is already available. Today I would like to introduce you to this useful pig.pig is Sql-like language, is built on the mapreduce of an advanced query language, Some operations are compiled into the MapReduce model's map and reduce, and users can define their own capabilities. Yahoo Grid Computing department developed another clone of Google's project: Sawzall. Supported operations ...

Cloud computing and data warehousing are a reasonable couple. Cloud storage can be scaled on demand, and the cloud can contribute a large number of servers to a specific task. The common function of Data Warehouse is the local data analysis tool, which is limited by calculation and storage resources, and is limited by the designer's ability to consider the new data source integration. If we can overcome some of the challenges of data migration, the problem can be solved by moving a data warehouse and its data analysis tools from dedicated servers in the datacenter to cloud-based file systems and databases. Cloud data management is often involved in loading and maintaining text in Distributed File systems ...

The Lunar New Year in early May is the annual Dragon Boat Festival, the Global Chinese Reunion Festival. As one of the largest traditional family reunion festival, probably most of the friends who go out to work and study can not be reunited with their families, on the one hand, the Dragon Boat Festival after all only 3 days, only a day more than the weekend holiday, if you choose to go home for the holidays most of the time may be delayed On the other hand, the public now face the persistent price rise and inflationary pressure, the cost of home festivals after all have to consider, more and more good at budget-minded friends may be caught in the tangle of home or left behind! .

Aiming at the problem of low storage efficiency of small and medium files in cloud storage system based on HDFS, the paper designs a scheme of small and medium file in cloud storage System with sequential file technology. Using multidimensional attribute decision theory, the scheme by combining the indexes of reading file time, merging file time and saving memory space, we get the best way of merging small files, and can achieve the balance between the time consumed and the memory space saved; The system load forecasting algorithm based on AHP is designed to predict the system load. To achieve the goal of load balancing, the use of sequential file technology to merge small files. Experimental results show that ...
