Question

which big data open source software was developed from google's mapreduce concept

Answer 1

Apache Hadoop is an open source software framework for storage and large scale processing of data-sets on clusters of commodity hardware. Hadoop is an Apache top-level project being built and used by a global community of contributors and users.

Answer 2

'Hadoop' was developed from google's map reduce concept.

Short notes on Hadoop:

Hadoop is a framework that allows for distributed processing of large data sets across clusters of commodity computers using a simple programming model.

Why do we need Hadoop:

Hadoop has the ability to analyze the data present in different machines at different locations very quickly and in a very cost effective way. It uses the concept of mapreduce which enables it to divide the query into small parts and process them in parallel. This is known as parallel computing.

Core components of Hadoop:

Core components of Hadoop are HDFS and MapReduce. HDFS is basically used to store large data sets and MapReduce is used to process such large data sets.

Advantages of Hadoop:

(i) Scalable

(ii) Cost Effective

Disadvantages of Hadoop:

(i) Security Concerns
