Question: Why Does The World Need Hadoop?

Is Hadoop Dead 2020?

Hadoop storage (HDFS) is dead because of its complexity and cost and because compute fundamentally cannot scale elastically if it stays tied to HDFS.

Data in HDFS will move to the most optimal and cost-efficient system, be it cloud storage or on-prem object storage..

Why Hadoop is used in big data?

Hadoop is the best solution for storing and processing big data because: Hadoop stores huge files as they are (raw) without specifying any schema. High scalability – We can add any number of nodes, hence enhancing performance dramatically. High availability – In hadoop data is highly available despite hardware failure.
