**Apache Hadoop** is an open-source framework designed for distributed storage and processing of large datasets across clusters of computers using simple programming models. It is designed to scale from a single server to thousands of machines, each offering local computation and storage. ### Key Components: 1. **Hadoop Distributed File System (HDFS)**: A distributed file system that stores data across multiple machines, providing high throughput access to application data. 2. **MapReduce**: A programming model for processing large datasets in parallel by dividing the work into smaller tasks that can be executed across the cluster. 3. **YARN (Yet Another Resource Negotiator)**: A resource management layer that handles scheduling and resource allocation across various applications running in the Hadoop ecosystem. ### Features: - **Scalability**: Can handle petabytes of data by adding more nodes to the cluster. - **Fault Tolerance**: Automatically replicates data across multiple nodes to ensure reliability and availability. - **Cost-Effectiveness**: Utilizes commodity hardware to reduce storage costs. ### Use Cases: Apache Hadoop is widely used for big data analytics, data warehousing, log processing, machine learning, and any application requiring storage and processing of large volumes of data. read less

Hello, I have completed B.com , MBA fin & M and 5 yr working experience in SAP PLM 1 - Engineering documentation management 2 - Documentation management Please suggest me which IT course suitable to my career growth and scope in market ? Thanks.
If you think you are strong in finance and costing, I would suggest you a SAP FICO course which is definitely always in demand. if you have an experience as a end user on SAP PLM / Documentation etc, even a course on SAP PLM DMS should be good.
