Hadoop Online Test
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.
Sample public questions
Capital Analytics, a digital marketing research firm, plans to move its research archives to a Hadoop cluster. They have a Hadoop cluster configuration with 1 NameNode and 3 DataNode(s).
For a replication factor of 3 and the data block size of 128 MB, what will happen if we store a file called '2010_archive' that is 150 MB in size?
You are given the task of configuring a Hadoop cluster with 2 NameNode(s) and 5 DataNode(s) to handle data generated by web crawlers.
Which options are correct for the given cluster and MapReduce implementations over it?

What others say
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.
