This document discusses the top 5 tasks of a Hadoop developer: 1) development and implementation of Hadoop applications, 2) loading data from disparate data sets, 3) performing analysis on big data, 4) securing data on Hadoop clusters, and 5) managing and deploying Hadoop clusters. It provides examples for tasks 2 and 3, discussing loading heterogeneous data from different sources and how companies analyze huge amounts of user data. The document is part of a presentation on Hadoop developer skills and roles.
A Hadoop developer is responsible for the actual coding/programming of Hadoop applications. Ideally the candidate should have at least 2 years of experience as a programmer
This role is synonymous to software developer or application developer - refers to the same role but in the Big Data domain
One component of Hadoop is MapReduce in which you need to write Java programs - so if you have basic knowledge of Java its sufficient - even if you don't have java knowledge but know any other programming language you can quickly catch up
Organizations that have not properly controlled access to their data sets are facing lawsuits, negative publicity, and regulatory fines
