Big Data and Apache Hadoop Practice Exam Questions

Big Data and Apache Hadoop Practice Exam

Big Data refers to huge volume of structured and unstructured data whichis generated at high speeds usually by social media, and IoT devices. The RDBMS are unable to handle big data hence, Apache Hadoop is used, which is an open-source software to store and manage Big Data by using a distributed storage system (HDFS) and parallel processing with the MapReduce.

Certification in Big Data and Apache Hadoop verifies your skills and knowledge in storing, managing and processing big datasets using Hadoop. This certification assess you in HDFS, MapReduce, Hive, Pig, and Spark.
