Guide to know about hadoop basic knowledge


Hadoop is a open, scalable, fault tolerant  source framework written in Java.It processes large volumes of data in a commodity hardware cluster. Hadoop is not just a storage system, but also a platform for data storage and data processing. Hadoop is a open source tool from Apache Software Foundation.The open source project means that it is available for free and we can also change its source code according to the requirements. Many Hadoop code is written by Yahoo, IBM, Facebook, Cloudera.


Hadoop provides an efficient structure for performing tasks on multiple cluster nodes. Cluster means a group of systems connected via LAN.Apache Hadoop provides parallel data processing while working on multiple machines simultaneously.Big Data Hadoop is very popular because Apache Hadoop captures over 90% of the big data market.

Apache Hadoop is not just a storage system, but also a platform for storing and processing data. These features of Hadoop make it a unique platform.Flexibility to store and extract any type of data, structured, semi-structured or unstructured. It is not limited by a single scheme.It overcomes when data of a complex nature are processed. Its scalable architecture divides workloads across multiple nodes. Another advantage is that its flexible file system eliminates ETL bottlenecks.The economic scale, as discussed, can be implemented in the basic hardware. Furthermore, its open source nature protects against the supplier's block.
