Hadoop Training and Certification in Dhaka, Bangladesh

Hadoop training provides learners with a deep understanding of the Hadoop ecosystem, focusing on distributed data processing and storage. It covers key components such as HDFS (Hadoop Distributed File System), YARN (Yet Another Resource Negotiator), and MapReduce for parallel data processing. Participants gain hands-on experience in setting up and configuring Hadoop clusters, managing large datasets, and performing analytics. The training also delves into related tools like Hive, Pig, and HBase, which are often used for querying, scripting, and managing data in Hadoop environments. By completing this course, professionals are equipped to design and deploy scalable, high-performance big data solutions in enterprise environments.
