Why MapReduce is used in Hadoop?

  • Analogous Processing
    • MapReduce processes the vast jobs of the datasets simultaneously
    • Thus it minimizes the time consumption taken for determining processes
  • Accessibility of Data
    • Data facsimiles are stored in every node and make them available even the system fails
  • Flexibility
    • This is because end users are permitted to access any app from every node presented and offers the high flexible framework
  • Cost-effective
    • This offers the users to a warehouse or processes a big data
  • Fault-tolerance
    • MapReduce is capable of handling the system let downs
  • Fast Process
    • Fast data process with massive volumes

The above listed are the important features ofMapReduce and the reason behind using them in Hadoop. We hope that you are getting the points involved in it. Here, we are going to demonstrate to you the role of Hadoop MapReduce for big data analytics. Shall we get into that? Here we go!

What is the Role of Hadoop MapReduce for Big Data Analytics?

  • Big Data Processing
    • Basic and multifarious tasks on the massive data are handled by the Hadoop MapReduce
    • Disk oriented storage platform is the best suit for assimilation of the data, summary of the data, filtering, and so on
  • Petabytes (PBs) or Terabyte (TBs) Processing
    • Gigabyte data volumes are outdated and now industries are subject to the PBs and TBs of volumes hence it is handled by the MapReduce
  • Various Data Storage Format
    • We can store the data in the forms of text, audio, video, images, and so on
    • These are enormous and thus cost is reduced significantly

These are the role of HadoopMapReduce in big data analytics. On the other hand, Hadoop frameworks are used in big data analytics. You might get a question on what are the frameworks of them.

Nodes in the Hadoop cluster are allotted by a fragment of datasets. The massive amount of data is segmented into chunks and subject to the algorithm application. Enormous datasets are getting processed within a fraction of seconds. Let’s have further explanations in the next phase.

How does MapReduce work in Hadoop?

  • Input – Mapper ( )
    • Map processors allow the input values as K1 (key-value) and give access to them
  • Run – Mapper ( )
    • K2 is the output value of the Map when K1 is given as input
  • Shuffle – Mapper Output ( )
    • As stated already K2 is the output value given to the processors to do tasks and it gives access to the entire key aspects
  • Run – Reducer ( )
    • It is done when the map generates the key values such as K2
  • End Output ( ) 
    • Retrieves entire reduced output and showcases the result as K2 as an end output

For example, we are going to demonstrate to you the K-means algorithm allied with MapReduce for massive data clustering, and their processes are stepped in the immediate section.
