The document outlines the scenarios when to use and when not to use Hadoop for big data processing. It emphasizes that Hadoop is unsuitable for real-time analytics, small structured datasets, and as a replacement for existing data infrastructures, while being effective for large unstructured datasets where response time is not a priority. Additionally, it highlights the importance of understanding Hadoop's complexities and the availability of various analytic tools for integration.

Slide 5Slide 5www.edureka.co/big-data-and-hadoopSlide 5 If you want to do some Real Time Analytics, where you are expecting result quickly, Hadoop should not be used directly Hadoop works on Batch processing, hence response time is high Day 1 Day 2 Day 3 Day 4 ......... ………. ……….

Slide 8Slide 8www.edureka.co/big-data-and-hadoopSlide 8 Hadoop is not a replacement for your existing data processing infrastructure After processing the data in Hadoop you need to send the output to relational database technologies today for BI, decision support, reporting etc It’s not going to replace your database, but your database isn’t likely to replace Hadoop either Different tools for different jobs Not a Replacement for Existing Infrastructure

Slide 9Slide 9www.edureka.co/big-data-and-hadoopSlide 9 Hadoop framework is not recommendable for small structured datasets as you have other tools available in market which can do this work quite easily and at a fast pace than Hadoop like MS excel, RDBMS etc For a small data analytics, Hadoop can be costlier than other tools Merge all the small files into one Multiple Smaller Datasets – Accepted Way

Slide 12Slide 12www.edureka.co/big-data-and-hadoopSlide 12 Many enterprises — especially within highly regulated industries dealing with sensitive data— aren’t able to move as quickly as they would like towards implementing Big Data projects and Hadoop “Example Health-care data used by Insurance companies to calculate premium” Where Security is the Primary Concern? They don’t have to hesitate though, as many of the security and compliance challenges are being continuously worked upon and can be surmountable (for example, by using Apache Accumulo on top of Hadoop).

15.
Slide 15Slide 15www.edureka.co/big-data-and-hadoopSlide 15 Your have different types of data : structured, semi-structured and unstructured The data set is huge in size i.e. several Terabytes or Petabytes You are not in a hurry for Answers Data Size and Data Diversity
16.
Slide 16Slide 16www.edureka.co/big-data-and-hadoopSlide 16 To implement Hadoop on you data you should first understand the level of complexity of data and the rate it is going to grow So we need a cluster planning, its may begin with building a small or medium cluster in your industry as per data (in GBs or few TBs ) available at present and scale up your cluster in future depending on the growth of your data Future Planning
