Hadoop has become the cornerstone of large data systems. Indeed, Hadoop developers know how to write applications that interact with Hadoop; but they also know how to build, operate, and troubleshoot large Hadoop clusters.

Hadoop is a large software stack. On one hand, it deals with low-level hardware resources, and on the other, it provides a high-level API to build software. As a result, a Hadoop developer not only develops software but also operates it.

Furthermore, a good grasp of algorithms and their runtime characteristics is essential to developing for Hadoop efficiently.
