how far this 51 tutorials are different from the course-certification that you mentioned at last in this video.I mean level of knowledge with this 51 tutorials and special course as you mentioned.Could you please give us clarity here.Thanks in advance! :-)

[@Room_no_209]

The best thing of this tutorial is explanation along with proper examples ,Which makes better understandable.

[@MAHAMAHOPADHYAY]

[@Trish0460]

Thanks for the introduction of big data & hadoop

[@45amitpatra]

Thanks Edureka for such video. Its indeed a very neat explanation. I have few questions though. 1. If Hadoop HDFS is a solution for big data, with that Replication Factor concept, isn't making the big data even bigger ? Say i have 2 TBs of data and while saving it to HDFS we need 6 TBs of space for a default Replication Factor as 3. In this way we need more storing space hence more slave nodes. Is it a drawback of the Hadoop framework ? Let me know if my understanding is wrong. 2. While loading into the HDFS , it maintains a replica of data which means we have duplicates in the overall file system. In MapReduce mechanism during reading the data, nowhere in the video it is mentioned that we receive duplicates. If it doesn't receive duplicates, then how it works internally to fetch only one set when we have other 2 sets present in the file system ? 3. What if we have a failure/outage in the Name node and Secondary Name Node servers ?

[@edurekaIN]

Hey Amit, thanks for checking out our tutorial! We are glad you found it useful. It won't be possible you give an explanatory answer here, I would suggest you to go through our Hadoop Architecture video in the below playlist: kzbin.info/aero/PL9ooVrP1hQOEmUPq5vhWfLYJH_b9jFBbR To answer your queries briefly: 1. Yes, more replication means more storage space. But this is something organization decides on how many replications to have. Because if you do not replicate your data and you loose it, that would be a huge loss. But spending money on slave nodes which are very cheap is a better option. 2. Data is stored on HDFS in "blocks" and namenode has all the information of which data is store where. A mapreduce job runs parallely on the datanodes and checks the nearest block (a replica) on that node and reads it. 3. In Hadoop 1.x, this was called as single point of failure. But in Hadoop 2.x, we have concept of High Availability, where we can have more than 1 namenode. If one namenode goes down, the other namenode gets activated and the hadoop cluster does not go down. Hope this helps. Cheers!

[@felipegutierre7037]

Totally Agree!

[@avinashnigam2270]

[@amanforyou9493]

Nice video sir and madam 👍 ✌

[@edurekaIN]

Hey, glad you liked the video. Do stay tuned for more updates . Cheers!

[@vishalaggarwal4860]

Hi Sir/Mam , very well explain.I want know that if i see all these tutorials , i it enough for me to crack an interview ?.As you explained in a very well manner. As i will also see mongoDB tutorials,.I am searching MongoDB tutorials since long time finally i got it.

[@edurekaIN]

Hey Vishal, thanks for checking out our tutorials! We're glad you liked them. While these KZbin tutorials will give you a good introduction to Big Data and Hadoop you will need structured training with hands-on to truly learn it. Also, since these are pre-recorded videos, you will lose out on doubt clarification and interaction with instructors who come with industry experience which will benefit you. We suggest that you take our Hadoop course which is a live course led by instructors and comes with 24x7 support. You will also get to work on practical assignments and a project towards the end of the course which will prepare you for job interviews. After all, practise is what makes you perfect. You can check out our course details here: www.edureka.co/big-data-and-hadoop. Please feel free to get in touch with us if you have any further queries. Cheers!

[@sagarbopche]

Hi I am working in Automobile field (CAE), is it useful for my carrer or this course is only for IT developers.

[@santhoshraina4549]

What are the skills required to learn big data

[@mmaller0319]

You mentioned HDFS can also work with structured data.Does this mean Hadoop can be seen as a probable replacement for RDBMS in certain use cases .I dont think so.RDBMS is still the best choice when it comes to structured data .Only when its unstructured or semi structured Hadoop is the #1 choice and for structured it can only be an add on rather than a replacement?What do you say?Nice session by the way.....

[@edurekaIN]

Hey Manjunath, thanks for checking out our tutorial! Yup, we agree with you that if you have structured data RDBMS is perfect. But, imagine a condition where you have all the three kinds of data i.e. structured, semi- structured as well as unstructured and you have to analyze it, then what would be your approach? Here, Hadoop comes into the picture, where you can dump any kind of data without pre-schema validation and easily analyze it. Also, try to understand that we are talking about archived data and not operational data. Hope this answers your query. Cheers!

[@harshitgupta2515]

what I have to install on my lappy to work on hadoop..as I install eclipse for java so for hadoop I have to install something like that??

[@edurekaIN]

Hey Harshit, this link will help you out: www.quora.com/How-do-I-set-up-Hadoop-Cluster-for-learning-Hadoop-using-Laptop Hope this helps :)

[@shammu16]

Thanks Saurabh & Reshma for nice presentation. Just i want to ask one thing that Teradata resource have to learn which part of hadoop which is best for his skills? I think Hive and Pig are good option or not? I need your suggestion on this. Thanks in advance.

[@edurekaIN]

Hey Sharmil, you are correct! If you are from Teradata background you may learn Pig and Hive in which you can run sql-like queries. You can also learn Spark SQL which is a part of Apache Spark ecosystem. Hope this helps. Cheers!

[@harshitgupta2515]

I only learn java core.so is it sufficient for start learning hadoop or I have to learn any other thing for starting with hadoop??

[@edurekaIN]

Hey Harshit, you can defnitely start learning as long as you hav basic functional knowledge of programming languages. Thanks :)

[@raghavmalhotra710]

Learn sql thats very easy..

[@naveedmohammad7437]

So edureca will charge for doing project for getting the certificate...I mean course charges and doing project are separately or once the course purchase all will come with that amount only ...can anyone clear my doubt please.. thanks in advance.

[@edurekaIN]

Hey Naveed, you won't have to pay anything extra for the project. Cheers!

[@AshishThakur-nx1qi]

what is the prerequisite to do this course

[@edurekaIN]

Basic programming language knowledge and Java knowledge is required. But you do not have to worry, we provide complementary self-paced training for all the pre-requisites. Hope this helps :)
