About the test

The Apache Hadoop online test assesses knowledge of the Hadoop framework, how to use it to configure Hadoop clusters, and how to perform distributed processing of large data sets across clusters of computers.

The assessment includes work-sample tasks such as:

  • Using MapReduce for processing large data sets.
  • Working with and configuring HDFS.
  • Taking advantage of Hadoop Streaming.

A good Hadoop developer or administrator should be familiar with Hadoop infrastructure, its configuration, and know how to run MapReduce operations on data sets.

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
