Surajit Paul has published ahow-to guide for Hadoops' Sqoopthat focuses on the Java APIs. Sqoop is an integral part of a Hadoop ecosystem, helping transfer data between NoSQL data storage and the traditional RDBMS. Numerous technical articles have been published featuring the Sqoop command-line interface (CLI) usage. However, as of Sqoop 1.4.3, there is not much insight publicly available about the usage of the Sqoop Java API. This article covers the usage of the Sqoop CLI, with additional emphasis on the Sqoop Java API, using an example of data from the Bombay Stock Exchange. The article is intended to provide preliminary exposure to technical architects, solution architects, technical managers, consultants, data scientists, technical leads, and developers interested in and working in the big data space.
