level of fault tolerance and is designed to be deployed on inexpensive (low-cost) hardware, and it provides high throughput (hi throughput) to access application data for applications with very large datasets (large data set). HDFs relaxes the requirements of (relax) POSIX and can access data in a stream (streaming access) file system. The core design of the Hadoop framework is: HDFs and MapReduce. HDFS pr

It took an entire afternoon (more than six hours) to sort out the summary, which is also a deep understanding of this aspect. You can look back later. After installing Hadoop, run a WourdCount program to test whether Hadoop is successfully installed.
