Program Plan Intro
Hadoop Distributed File System (HDFS):
- Hadoop Distributed File System (HDFS) is the primary data storage systems usually used by the Hadoop applications.
- It was developed as an infrastructure for the Apache Nutch web search engine project and now it is an Apache Hadoop subproject.
- It includes a NameNode and DataNode architecture to implement a distributed file system that is capable of providing high-performance access to data across Hadoop clusters.
