What is Hadoop and Why is it So Important?
Apache Hadoop is an open-source framework designed for distributed storage and processing of large datasets across clusters of computers. It is capable of handling both structured and unstructured data with scalability, fault tolerance, and efficiency.
Core Components of Hadoop:
- HDFS (Hadoop Distributed File System) is used for storing large files across multiple machines understanding concepts like this highlightsHDFS (Hadoop Distributed File System) is used for storing large files across multiple machines understanding concepts like this highlights Why Scala Training is Important, especially when working with big data tools like Hadoop and Spark, especially when working with big data tools like Hadoop and Spark.
- MapReduce : A processing model for parallel computation on large data sets.
- YARN (Yet Another Resource Negotiator): Manages resources in a Hadoop cluster.
- Hadoop Common: Shared utilities and libraries required by other Hadoop modules.
- Store huge volumes of data cost-effectively.
- Perform complex data analysis using commodity hardware.
- Scale their systems as data grows.
- Gain insights that drive business decisions.
Hadoop is important because it allows organizations to:
Its ability to handle large-scale data processing in real time makes Hadoop central to Big Data strategies worldwide.
