What Is Hadoop?
Hadoop is the framework which allows the distributed processing of large data sets across the clusters of commodity computers using a simple programming model. It also has the ability to store and analyze the data occurred in different machines at different locations quickly with effective cost and uses MapReduce concept which divide the query. Unstructured data such as log files, Twitter feeds, media files, and data from the internet are more relevant to the businesses. Regularly, there was a large amount of unstructured data that is being dumped into our machines. The main challenge is to retrieve and analyze this big data in the organizations instead of storing the large data sets.
Key Features of Hadoop
Due to its power of distributed processing, Hadoop would handle large volumes of structured and unstructured data more efficiently than the traditional enterprise data warehouse. Hadoop is open source and therefore, it also run on commodity hardware.
