What are the different features of Hadoop.

Answer 1

Listed in many Big Data Interview Questions and Answers, the best answer to this is –

1. Open-Source – Hadoop is an open-sourced platform. It allows the code to be rewritten or modified according to user and analytics requirements.
2. Scalability – Hadoop supports the addition of hardware resources to the new nodes.
3. Data Recovery – Hadoop follows replication which allows the recovery of data in the case of any failure.
4. Data Locality – This means that Hadoop moves the computation to the data and not the other way round. This way, the whole process speeds up.
