    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."
    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!

    Customer Review:
    Michael Harkins, System Architect, Hortonworks says: “The courses are top rate. The best part is live instruction, with playback. But my favourite feature is viewing a previous class. Also, they are always there to answer questions, and prompt when you open an issue if you are having any trouble. Added bonus ~ you get lifetime access to the course you took!!! ~ This is the killer education app... I've take two courses, and I'm taking two more.”

    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 ?

      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:
      czcams.com/play/PL9ooVrP1hQOEmUPq5vhWfLYJH_b9jFBbR.html
      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!

      Hey Jhanvi, you can surely think about mving in to this domain. To accomplish that, you will need to have strong knowledge of the Big Data environment. Also, learning Java would be an essential. You can check out our Big Data course here: www.edureka.co/big-data-and-hadoop
      Hope this helps :)
