Data is deluging today’s enterprise organizations from ever-expanding sources and in ever-expanding formats. To gain insight from this valuable resource, organizations have been adopting Apache Hadoop with increasing momentum. Now, the most successful players in big data enterprise are no longer only utilizing Hadoop “core” (i.e., batch processing with MapReduce), but are moving toward analyzing and solving real-world problems using the broader set of tools in an enterprise data hub (often interactively) — including components such as Impala, Apache Spark, Apache Kafka, and Search. With this new focus on workload diversity comes an increased demand for developers who are well-versed in using a variety of components across the Hadoop ecosystem.
Due to the size and variety of the data we’re dealing with today, a single use case or tool — no matter how robust — can camouflage the full, game-changing potential of Hadoop in the enterprise. Rather, developing end-to-end applications that incorporate multiple tools from the Hadoop ecosystem, not just the Hadoop core, is the first step toward activating the disparate use cases and analytic capabilities of which an enterprise data hub is capable. Whereas MapReduce code primarily leverages Java skills, developers who want to work on full-scale big data engineering projects need to be able to work with multiple tools, often simultaneously. An authentic big data applications developer can ingest and transform data using Kite SDK, write SQL queries with Impala and Hive, and create an application GUI with Hue. (more…)
