A course on Big Data & Hadoop provides specialized training on the Apache Hadoop framework, a foundational technology for storing and processing massive datasets, which are too large or complex for traditional database systems. The curriculum dives deep into the core components of the Hadoop ecosystem, including Hadoop Distributed File System (HDFS) for data storage, MapReduce for parallel processing, and YARN for cluster resource management. It also typically covers other related tools like Hive, Pig, and HBase. This training is crucial for IT professionals and new graduates who want to enter the high-demand field of Big Data. It’s an essential skill for anyone aiming to become a Big Data Engineer or Data Scientist.
