Apache Hadoop Key Features:
- Accessible: Hadoop runs on large clusters of commodity machines or on cloud computing services such as Amazon’s Elastic Compute Cloud (EC2).
- Robust: Because it is intended to run on commodity hardware, Hadoop is architected with the assumption of frequent hardware malfunctions. It can gracefully handle most such failures.
- Scalable: Hadoop scales linearly to handle larger data by adding more nodes to the cluster.
- Simple: Hadoop allows users to quickly write efficient parallel code.
