Docker容器CPU资源分配对Hadoop性能的影响分析

Analysis for the Impact of Docker Container CPU Resource Allocation on Hadoop Performance

Docker容器是目前云计算中使用最广的虚拟化技术,而Hadoop是使用广泛的大数据处理技术。如何高效合理地为Docker容器分配CPU资源,提高Hadoop在容器内运行的性能,是用户关注的一个问题。文中评估了CPU资源分配对Hadoop性能的影响,并分析了造成这些影响的原因。

Docker container is currently the most widely used virtualization technology in cloud computing,while Hadoop is a extensively used big data processing technology.How to allocate CPU resources to Docker containers efficiently and reasonably and improve the performance of Hadoop running in the container is a problem that users pay attention to.This paper evaluates the impact of CPU resource allocation on Hadoop performance,and analyzes the reasons for these effects.
