  2. In reference to High Availability of NameNode, I only heard you talk about passive NameNode picking up when the NameNode fails and that the Secondary NameNode serves only as a backup and will work only when configure to replace the active NameNode. My question is in Hadoop 2.X is there nothing like the StandBy NameNode that picks up when the Active NameNode fails?

  3. Hi, first of all thanks for uploading this very informative series on Big Data, it is really helpful.
    I have a question like what kind of operations can we perform with unstructured data / binary / image/ video files using the hadoop stack?
    I have seen examples where they have converted semi structured files such as logs and json to tabular format using regular expressions.
    But what can we do with video files for examples?
