Welcome to Lesson 4 - Intro to Hadoop and MapReduce

  • 0:01 - 0:04
    Hi, my name is Andy and I'm a instructor
  • 0:04 - 0:07
    at Udacity. I worked with Sara and Ian and
  • 0:07 - 0:11
    Ngundega to help prepare this lesson and today I'm
  • 0:11 - 0:13
    going to deliver it for you. So, let's get
  • 0:13 - 0:17
    started. Up to this point you've familiarized yourself with
  • 0:17 - 0:19
    MapReduce, you've written some mapper code, some reducer code.
  • 0:21 - 0:23
    And you probably have a decent understanding of what's
  • 0:23 - 0:27
    going on behind the scenes. But you might not
  • 0:27 - 0:30
    yet know when to use MapReduce to solve a
  • 0:30 - 0:32
    problem. And that's what we're going to try and get at
  • 0:32 - 0:34
    in this lesson. We're going to give you a bunch of
  • 0:34 - 0:37
    problems to solve and actually, each of these problems has
  • 0:37 - 0:41
    been deliberately selected, because each of these problems actually
  • 0:41 - 0:45
    represents some larger class of problems. In reality, the problems
  • 0:45 - 0:48
    you're likely to run into on the job are going
  • 0:48 - 0:52
    to fall into one of these certain classes of problems,
  • 0:52 - 0:54
    which is very convenient because it means you
  • 0:54 - 0:58
    can apply a sort of boiler plate solution, with
  • 0:58 - 1:03
    some modifications. These boilerplate solutions we call design patterns,
  • 1:03 - 1:06
    and they're really helpful. In this lesson we'll learn
  • 1:06 - 1:08
    about some of these design patterns, and we'll
  • 1:08 - 1:12
    practice using them on various problems. We're not going to
  • 1:12 - 1:14
    get into the details of where the patterns came
  • 1:14 - 1:17
    from, or why they look the way they do,
  • 1:17 - 1:19
    but, at the very least, at the end of this
  • 1:19 - 1:22
    lesson, you will have, well for one, you'll practice using these
  • 1:22 - 1:25
    patterns and you also have a resource. That you can always
  • 1:25 - 1:28
    come back to whenever you run into a problem that can
  • 1:28 - 1:31
    be solved using one of these patterns. If this kind of
  • 1:31 - 1:34
    stuff is really interesting to you, you should definitely check out
  • 1:34 - 1:38
    a book called MapReduce Design Patterns. It's written by Donald Miner
  • 1:38 - 1:43
    and Adam Shook and it's really interesting. Anyways, let's get started.
