Hadoop Distributed File System (HDFS)
HDFS is a distributed file system that provides access to data across Hadoop clusters. A cluster is a group of computers that work together.
Like other Hadoop-related technologies, HDFS is a key tool that manages and supports analysis of very large volumes petabytes and zetabytes of data.
What is YARN?
YARN is the acronym for Yet Another Resource Negotiator. YARN is a resource manager created by separating the processing engine and the management function of MapReduce.
It monitors and manages workloads, maintains a multi-tenant environment, manages the high availability features of Hadoop, and implements security controls
