Quick Answer: How Difficult Is Hadoop?

Is Hadoop dead?

There’s no denying that Hadoop had a rough year in 2019.

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

For real-time insights, users need immediate and elastic compute capacity that’s available in the cloud..

Can I learn Hadoop without knowing Java?
