Hadoop's explosion over the last few years has been phenomenal. One estimate puts its growth at nearly 60 percent year-over-year, with a market of $50 billion by 2020. As the furious uptake has created demand for Hadoop vendors, an accompanying need for vendors selling Hadoop data migration tools and services is also shaping up.
In theory, getting data into and out of Hadoop is well within the capacity of both the software and its users. Apache's Sqoop project was created to deal with Hadoop import and export, with native support for the usual suspects: MySQL, Oracle, PostgreSQL, and HSQLDB. But not everyone is comfortable doing the work themselves, so vendors are offering polished import/export solutions that require less manual labor.
