Problems solved by technology

However, in the Hadoop big data storage process, due to the flaws in the design of the Hadoop architecture, although Hadoop is a distributed storage, but because the NameNode (the namespace that manages the file system) is a single node, the NameNode itself inevitably has a single point of failu

Abstract

The invention provides a distributed storage system-based NameNode switching method and a distributed storage system-based NameNode switching device. The method comprises: backing up storage data in a master NameNode to a slave NameNode in a preset data backup manner in order to complete the data synchronous storage process; detecting whether the master NameNode stops providing data services by the slave NameNode; and determining whether the virtual IP address connected with the master NameNode is to be switched and connected to the slave NameNode in accordance with the detection result. On the one hand, the technical solution can effectively eliminate a single point of failure in the existing Hadoop-based distributed storage system and improve the availability of the system; and on the other hand, when the master NameNode fails, the master NameNode can be quickly switched to a backup NameNode, which effectively shortens the time of NameNode service restoration so that NameNode can provide services in real time, thus improving the stability of the distributed storage system.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular, to a NameNode switching method based on a distributed storage system and a NameNode switching device based on a distributed storage system. Background technique [0002] At present, after cloud computing, big data has become a new trend that has attracted much attention in the field of science and technology. Big data needs to effectively process a large amount of data that can tolerate time. Among them, the data includes: Massive Parallel Processor (MPP) Databases, data mining grids, distributed file systems, distributed databases, cloud computing platforms, the Internet, and scalable storage systems. Apache Hadoop is an open source distributed system infrastructure developed by the Apache Foundation. Users can develop distributed programs on the basis of Hadoop and store data in a distributed manner without knowing the underlying details of the distribution, so that ...
