6 Reasons Why Big Data Career is a Smart Choice

Confused whether to take up a career in Big Data or not? Planning to invest your time in getting certified and to acquire expertise in related frameworks like Hadoop, Spark etc. and worried whether you are making a huge mistake? Just spend a few minutes reading this blog and you will get six reasons on why you are making a smart choice by selecting a career in big data.

Why Big Data?

There are several people out there who believe that Big Data is the next big thing which would help companies to spring up above others and help them position themselves as the best in class in their respective sectors.

Companies these days generate a gigantic amount of information irrespective of which industry they belong to and there is a need to store these data which are being generated so that they can be processed and not miss out on important information which could lead to a new breakthrough in their respective sector.  Atul Butte, of Stanford School of Medicine, has stressed the importance of data by saying “Hiding within those mounds of data is the knowledge that could change the life of a patient, or change the world”. And this is where Big Data analytics play a very crucial role.

With the use of Big Data platforms, a gigantic amount of data can be brought together and be processed to develop patterns which would help the company in making better decisions which would help them to grow, increase their productivity and to help create value to their products and services.

How to Install Hortonworks Data Platform – HDP 2.6 on AWS

In this post, we will show you how you can install Hortonworks Data Platform on AWS.

You can also watch the video of this tutorial here

 

We start with three machines. We could install Hadoop on these machines by manually downloading and configuring them, but that’s very insufficient. So either we could use Cloudera manager or Ambari. In this tutorial, we are going to use Ambari.

On the first machine, we are going to install the Ambari server. For that, we need to buy these three instances at Amazon and we will follow the Ambari guidelines.

Ambari will then install all the components that are required in other two machines.

Please note, we will use 16 GB ram machines so that installation goes smoothly. 

Let’s get started.

A Successful Machine Learning Bootcamp at Singapore

Cloudxlab has conducted many successful online events on Machine Learning and Big Data, for it is relatively easy to attend so many attendees simultaneously. Furthermore, it eliminates the need for a tiring visit to the event location. One can simply log in from the comfort of one’s house and start learning.

Sure, online events have their own perks. But it hasn’t stopped us to conduct offline events. Our Machine Learning session at R.V College of engineering was one such successful example.

This time, we wanted to conduct a little bigger event, therefore Cloudxlab joined hands together with IOTSG and National Singapore university, enterprise to organize another successful Machine Learning Bootcamp.

The Venue

CloudxLab was organizing the Machine learning Bootcamp for the first time in Singapore. To be frank, we were a little nervous as we did not know how welcoming the country is. But all our minor doubts were cleared once we experienced the warm welcome from everyone there. So much so that we would like to do one more Bootcamp in Singapore in near future.

National Singapore University was very cooperative in helping us to organize the Bootcamp in their campus.

The Pursuit of Education – A Story of Strength

Today, we will not talk tech or discuss our regular tutorials. Instead, we will take you on a different journey – a journey about strength, a journey about hope, and a journey on life.

It was a regular working day for us when an email caught our attention. It was from an individual who faced unimaginable hardships in his life but still hopes for a better future by executing his passion for learning.

His message was rather long and it clearly showed that he was in desperate need of a higher education. We thought he was a student, and we offered him the student’s discount on one of our self-paced courses on Big Data. But much to our surprise, he was not in a state to pay even the discounted price.

We were not clear on why he would be requesting for a free course. However, we came to know about the kind of hardship that he had recently gone through, and about his real mission to move back to his native place and help poor and needy students by providing free education.

He was a Rohingya refugee and had lost his entire family in the recent clashes of Myanmar. He managed to survive the traumatic ordeal but thinking of a new life was more of an impossible dream for him. However, he stepped up and decided to move on with his life.

He wanted to continue his education, and therefore, started to look out for a Big Data course that he could do for free because of his terrible financial crisis. He came across CloudxLab and got in touch with us explaining his situation. He also mentioned that he wanted to help the needy back in his country for which he needed to go through the course.

We were much in awe of this person’s strength of mind. He came across as an epitome of strength who is ruthlessly following his dream despite all odds and ordeals.

We offered him our course at no cost, but we did not know how much it meant to him until he sent his reply:

I can’t explain my feelings in words how much happy I am now. You are an angel for me who help me to stand on my feet. Sir thank you for believing in me and giving me a chance to continue my dream. I promise I will do my best and complete the course as fast as I can. Thank you.

This is probably our biggest achievement as a team.

We salute this individual for his unthinkable strength in facing such a catastrophe in his life while nurturing a selfless desire to help others. We wish him good days ahead and hope that he completes his education and embarks on the journey to help his people.

A Simple Tutorial on Scala – Part – 2

Welcome back to the Scala tutorial.

This post is the continuation of A Simple Tutorial on Scala – Part – 1

In the Part-1 we learned the following topics on Scala

  • Scala Features
  • Variables and Methods
  • Condition and Loops
  • Variables and Type Inference
  • Classes and Objects

Keeping up the same pace, we will learn the following topics in the 2nd part of the Scala series.

  • Functions Representation
  • Collections
  • Sequence and Sets
  • Tuples and Maps
  • Higher Order Functions
  • Build Tool – SBT

Functions Representation

We have already discussed functions. We can write a function in different styles in Scala. The first style is the usual way of defining a function.

scala> def add(x : int, y : int) : Int = {
         return x + y
       }

Please note that the return type is specified as Int.

In the second style, please note that the return type is omitted, also there is no “return” keyword. The Scala compiler will infer the return type of the function in this case.

scala> def add(x : int, y : int) = { //return type is inferred
         x + y //"return" keyword is optional
       }

If the function body has just one statement, then the curly braces are optional. In the third style, please note that there are no curly braces.

def add(x : Int, y : Int) = x + y

A Simple Tutorial on Scala – Part – 1

Welcome to the Scala tutorial. We will cover the Scala in two-part blog series. In this part, we will learn the following topics

  • Scala Features
  • Variables and Methods
  • Condition and Loops
  • Variables and Type Inference
  • Classes and Objects

For better understanding, do hands-on with this tutorial. We’ve made this post in such a way that the reader will find easy to follow the tutorial with hands-on.

Scala Features

Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way.

It is a statically typed language. Which means it does type checking at compile-time as opposed to run-time. Let me give you an example to better understand this concept.

When we deploy jobs which will run for hours in production, we do not want to discover midway that the code has unexpected runtime errors. With Scala, you can be sure that your code will not give you unexpected errors while running in production.

Since Scala is statically typed we get performance and speed over dynamic languages.

How is Scala different than Java?

Unlike Java, in Scala, we do not have to write quite as much code to perform simple tasks and its syntax is very similar to other data-centric languages. You could say that Scala is the modified version of Java with less boilerplate code.

A Simple Tutorial on Linux – Part-2

This post is the continuation of A Simple Tutorial on Linux – Part-1

In the Part-1 we learned the following topics on Linux.

  • Linux Operating System
  • Linux Files & Process
  • The Directory Structure
  • Permissions
  • Process

Keeping up the same pace, we will learn the following topics in the 2nd part of the Linux series.

  • Shell Scripting
  • Networking
  • Files & Directories
  • Chaining Unix Commands
  • Pipes
  • Filters
  • Word Count Exercise
  • Special System commands
  • Environment variables

Writing first shell script

A shell script is a file containing a list of commands. Let’s create a simple command that prints two words:

1. Open a text editor to create a file myfirstscript.sh:

nano myfirstscript.sh

2. Write the following into the editor:

#!/bin/bash
name=linux
echo "hello $name world"

Note: In Unix, the extension doesn’t dictate the program to be used while executing a script. It is the first line of the script that would dictate which program to use. In the example above, the program is “/bin/bash” which is a Unix shell.

1. Press Ctrl +x to save and then “y” to exit

2. Now, by default, it would not have executable permission. You can make it executable like this:

chmod +x myfirstscript.sh

3. To run the script, use:

./myfirstscript.sh
