Apache Hadoop is an open source, Scalable, and Fault-tolerant framework written in Java. It efficiently processes large volumes of data on a cluster of commodity hardware. Hadoop is not only a storage system but is a platform for large data storage as well as processing. This Big Data Hadoop tutorial provides a thorough Hadoop introduction.

What is Hadoop?
Hadoop is an open-source tool from the ASF - Apache Software Foundation. Open source project means it is freely available and we can even change its source code as per the requirements. If certain functionality does not fulfill your need then you can change it according to your need. Most of Hadoop code is written by Yahoo, IBM, Facebook, Cloudera.

It provides an efficient framework for running jobs on multiple nodes of clusters. Cluster means a group of systems connected via LAN. Apache Hadoop provides parallel processing of data as it works on multiple machines simultaneously.

By getting inspiration from Google, which has written a paper about the technologies. It is using technologies like Map-Reduce programming model as well as its file system (GFS). As Hadoop was originally written for the Nutch search engine project. When Doug Cutting and his team were working on it, very soon Hadoop became a top-level project due to its huge popularity.

Apache Hadoop is an open source framework written in Java. The basic Hadoop programming language is Java, but this does not mean you can code only in Java. You can code in C, C++, Perl, Python, ruby etc. You can code the Hadoop framework in any language but it will be more good to code in java as you will have lower level control of the code.

Big Data and Hadoop efficiently process large volumes of data on a cluster of commodity hardware. Hadoop is for processing huge volume of data. Commodity hardware is the low-end hardware, they are cheap devices which are very economical. Hence, Hadoop is very economic.

Azur Lane: Garry's Mod by LaResistance19401944

Hello there, Wattpad community My name is LaResistance and this is my very first story. Since this is the first story I am making, don't expect it to be off high quality but I will try my best. This story is going to comprise of some events that took place in the anime of Azur Lane, and I am also going to make the main character well you could say a soldier from Garry's Mod since I want him to from the time of the fan-made film back in the 2000's call "War Of The Servers". You should check it out it is pretty good for a movie made when Garry's Mod was still in it's early stages. Here is the link to it, you better watch it or you are going in this story blind : https://youtu.be/ppUl_CBuyz8. God bless the people who made that movie man god bless them. Enough talking, onto the story. The year is 2021, the Mingbags are back and Garry's Mod is once again at war. This time new updates were added which made the conflict between both the Players and the Mingbags very bloody. We follow a player who was ranked up to Sargent class. Instead of admins taking over the jobs as soldier, they are still able to but other players are able to enlist into the Digital Garry's Mod Militia or the Garry's Mod military. This player is named SirStonksMan and he is a Polish player. He was about to be sent out onto a offensive against the Mingbags but discovered a lab. What he and his comrades didn't know was their was a portal there and they accidently activated it send Sgt. Stonks into another universe. How will he proceed and what is he to do?

INNOCENCE LOST (Rewriting) by Annie91writes

"Forever, I had stayed silent, closed off, cut by the doldrums of family politics and societal pressures. Buried under biased judgements, I dwarfed to insignificant heights. But, inside the blaze fought to seize power-an inferno. Raging flames fuelled to perfection-burning hot with wrath, scorched by hindered expectations and smothered under unrealized dreams. Beauty and the beast reside together, working in unison. When one sleeps another awakes. Every beauty has a beast, brought alive by a trigger. I was a beauty, but then shit happened. Still, I smile. I laugh. I cook. I sew. I make love. I'm a good girl. But, good girls aren't necessarily good, it's just that they aren't bad in the traditional way. ---------------------------------------------------------- "You will get used to it...just a matter of time", her mother stated. "Every girl goes through this phase." It's easier said than done. For Sreya, the statement failed to shed a warm light, never had. And growing up in Swarupnagar, a suburb in one of the most dead corners of Kolkata didn't contribute much to the situation either. Dreams aren't bound, neither by words nor by limitations. Sreya dreamt for just one thing-get out of the system and create a life of her own. But, not every dream can be fulfilled; even worse, what if they come at a cost? What happens when your past that you skilfully camouflage haunts as your worst nightmare and the institution of marriage that people hold as sacred is rigged at the very core! Set against a backdrop of Metropolitan Kolkata, this tale of lust, ambition, addiction and revenge creates a wild concoction that is sure to leave readers' minds content, fulfilled and craving for more. ---------------------------------------------------------- Disclaimer: MATURE CONTENT Start date: 13/08/2021 End date: 30/9/2021

PGDH4 by vedhanshacharya

(completed) Jack did not want to look at the world like everybody else. He could not. Actually That's what everyone does-They see what they chose to see. i think that affects us more than we think. it is strange. enclosed in the same space. But passing through our senses, our mental perception and cognition it becomes unsimilar; altered. We always perceive this world through the same filter. Ours. in a way, we ourselves create the world we live in. All totally different and vivid. Making us special to ourselves. Guess we are. We are unique. May be the only one thing we all share is uniqueness. So that means: being unique is just not unique? There are more people in this world than we can count. And much more creatures that possess life and an independent indifferent mind.The universe is too vast. Each of us even with our unique grasp and judgement may be insignificant to the limitless cosmos. but each of us might possess something that streaches far greater. Our dreams. Our ideality and imagination. They are boundless. We can see the edge of the universe even if it may not exist. We can believe. We can create. We can control. We are the masters of our own mind. Our own world. And this universe may be insignificant against that power we all have. ................................
