About the test

The Apache Hadoop online test evaluates a candidate's 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.

It's an ideal test for the pre-employment screening of candidates applying for roles such as Hadoop developers, testers, and administrators.

This test requires candidates to answer questions based on Hadoop infrastructure, its configuration, and running MapReduce operations on data sets.
