MapReduce is a high-performance batch processing distributed computing framework for parallel analysis and processing of massive data. Compared with traditional data warehousing and analysis techniques, MapReduce is suitable for dealing with various types of data, including structured, semi-structured, and unstructured data. The data is at terabytes and PB levels, and at this level, traditional methods are often unable to process data. MapReduce divides the analysis task into two categories: a large number of parallel Map tasks and a Reduce rollup task. Map task runs in multiple suits ...

Recently, a question was raised on Quora about the differences between Hadoop Distributed file systems and OpenStack object storage. The original question is as follows: "HDFS (Hadoop Distributed File System) and OpenStack object Storage (OpenStack object Storage) all seem to have similar purposes: to achieve redundant, fast, networked storage. What are the technical features that make the two systems so different? Is it significant that these two storage systems eventually converge? "After the question was raised, soon ...

What is the difference between a quick deployment of Windows Azure and a distributed deployment? Where do the two deployment types need to be used separately? The Windows Azure Pack is deployed in two ways: rapid deployment and distributed deployment are very similar, but their purpose is quite different. Rapid deployment refers to installing Windows Azure package components on a system with a web platform installer. The advantage of this type of deployment is the simplicity of deployment and the very low hardware requirements that are typically used for testing in low flow labs or ...

The model picks ...

Distributed collaboration is indispensable in distributed application, and it is the role of coordinator, that is, to separate the responsibility of multi-machine synergy from distributed application, so as to reduce the coupling of system and enhance the expansibility. The zookeeper of Apache, Google's chubby are the implementation of distributed collaboration. Fourinone is actually an upgraded version of Zookeeper, which implements all of zookeeper's functions with minimal code and tries to use a simpler, more powerful application ...

Research and implementation of distributed storage based on HDFS Weishukang This paper analyzes the structure and operation mechanism of HDFS, points out some design defects, and improves the HDFS's copy strategy, the main work is as follows: (1) HDFS The default static replica redundancy policy does not distinguish hot data. The node that holds the data is a bottleneck in the cluster. To solve this problem, a dynamic redundancy strategy based on data heat is proposed in this paper. This strategy counts and predicts access to each file, and the statistical cycle of each file is visited ...
