Organizations use Hadoop to gain capabilities such as scalability, cost-effectiveness, flexibility, and fault tolerance in handling big data.
Hadoop can handle not only structured data that fits well into relational tables and arrays but also unstructured data. A partial list of this type of data Hadoop can deal with are:
- Computer logs
- Spatial data/GPS outputs
- Industrial sensor data
- Images, videos, MP3s
- Social Media updates
- Weblogs, forum comments, etc.
