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.
Sample public questions
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?
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?
