There is a concept of an abstract file system in Hadoop that has several different subclass implementations, one of which is the HDFS represented by the Distributedfilesystem class. In the 1.x version of Hadoop, HDFS has a namenode single point of failure, and it is designed for streaming data access to large files and is not suitable for random reads and writes to a large number of small files. This article explores the use of other storage systems, such as OpenStack Swift object storage, as ...

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 ...

When cloud services are running smoothly and service level agreements (SLAs) are in place, business parties, businesses, and institutions may want to transfer data from cloud storage to different providers, but find it impossible to do so for some reason. One reason is that the data format required for API calls to store data in the cloud is incompatible with, or not interoperable with, API calls used by different providers to store data in the cloud. As a result, the business side will be confronted with data transmission failure due to the format used by different providers before choosing a provider to provide cloud services ...
