Why Learn Hadoop?
Big Data! A Worldwide Problem?
According to Wikipedia, "Big data is collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications." In simpler terms, Big Data is a term given to large volumes of data that organizations store and process. However, it is becoming very difficult for companies to store, retrieve and process the ever-increasing data. If any company gets hold on managing its data well, nothing can stop it from becoming the next BIG success!
The good news is - Hadoop has become an integral part for storing, handling, evaluating and retrieving hundreds of terabytes, and even petabytes of data.
- - - - - - - - - - - - - -
Opportunities for Hadoopers!
Opportunities for Hadoopers are infinite - from a Hadoop Developer, to a Hadoop Tester or a Hadoop Architect, and so on. If cracking and managing BIG Data is your passion in life, then think no more and Join Edureka's Hadoop Online course and carve a niche for yourself!

[@shahinabanu2375]

THANK YOU

[@ge_song5]

Nice work!

[@varaprasad8378]

Hi Reshma, what exactly happening when both WRITE and READ operations performed on a block at same time?

[@edurekaIN]

HDFS follows WORM i.e. Write Once Read Many policy. Once the block that has been written to HDFS can't be edited or modified. Hence, you will never be able to write to the data blocks already residing in HDFS. And yes, multiple user can perform read operation concurrently on same data blocks. Hope this helps :)

[@sushruthlokam]

Hi Edureka, The explanation of MapReduce is awesome.. I have one question, Most of all SQL operations are done in PIG then where we will use the HIVE and what are the use-cases of HIVE.

[@edurekaIN]

Hey Sushruth, "www.edureka.co/blog/hive-tutorial/ This blog might help you out! Good luck."

[@edurekaIN]

Hey Harshit, these videos are of basic/intermediate level which has clear explanation of all the concepts used in Apache Hadoop. If you truly want to master these technology with good hands-on experience that check out this link: www.edureka.co/search/Hadoop Hope this helps :)

[@subramanyam.d24m56]

[@adityareddy9286]

Hi, at 56:36 Can you explain what are the two blank spaces u are talking about.Thank you. Btw very good presentation.

[@edurekaIN]

Hey Aditya, sorry for the delay. If you see the values column in the input text file, each tuple has three words and 2 spaces between the three words. Hope this helps!

[@abhisheksharma6617]

Given the fact that what a top notch presenter Reshma is, how I wish the map reduce was in Python!!!

[@jksharma7]

very good

[@prashantkudire3544]

Commodity hardware means ?

[@RanveerSingh-gj5tb]

@43:25 why block B had more number (6) to traverse compared to block A (4).. means why is it going via switch? Is it because of the racks..

[@edurekaIN]

Hey Ranveer, that is just a demonstration. Actually all inter-rack communications are done via a switch. Hope this helps :)

[@sriniub7594]

Thanks Reshma for your instructive and clear video tutorial, I joined hadoop Big Data course in edureka last month, I want to learn PIG programming end to end [PIG scripting], Can you please advice where i can learn more PIG scripting concepts.

[@edurekaIN]

Hi Sriniu, firstly thanks for joining our Big Data Hadoop course, welcome to our learner family. Check out this video on Pig Tutorial: kzbin.info/www/bejne/fXiQh4Wja72hhM0 Here are few blogs also on Pig: www.edureka.co/blog/pig-tutorial/ Cheers!

[@jaykrishna2371]

I am learning hadoop in the 53 videos presented by edureka.. what is the certification procedure after completing these 53 videos???

[@edurekaIN]

Hey Jay, once you are done understanding he basics and are ready to master hadoop then, check out our Big Data Hadop course here: www.edureka.co/big-data-and-hadoop The course description, curriculum, fees, batches and other details are mentioned there. Give it a read and let us know if you have any query. Cheers :)

[@shriraml]

Hey Reshma. That was very much informative.. How about the job openings outside for PIG scripting with basic knowledge as I am very much new to BIG data but little older with SQL knowledge.

[@edurekaIN]

Hey Ram! You can drop down your email and we will get in touch with more information on this. Thanks :)

[@tushargoyal4393]

yours tutorials are very nice i understand everything.. but i want that csv file u used in the tutorials

[@edurekaIN]

Hey Tushar, we are glad you liked our video. Mention your email address and we will send the files over. Cheers :)

[@mathstube1802]

Where to BIG data get stored? isit in Hadoop? So Hadoop is like hardware drive which store data by means of HDFS??

[@saurabhiim]
