This will start the download of the dmg file. To download the docker dmg file, go to Docker Store and click on the Get Docker download button. Now that we have a basic idea about what Hadoop and Docker is, we will start installing them on our machine.įirst we will download the docker dmg file. You can literally spawn up a container for your application in a fraction It is more flexible, fast, powerful and less resource consuming. It can be thought of like a Virtual Machine running tool(like VMWare, Virtual box), but Docker is a tool to provision containers to run different applications without Now, lets talk a little bit about Docker. Mapping is the first phase in Hadoop processing in which the entire data is split in tuples of keys and values.Īfter this operation these key value tuples are passed to the shuffler which collects the same type keys from all the mappersĪnd send them to the reducers which finally combine them and writes the output in a file. Stored on the data nodes and the metadata (data about data) is stored on the Name node. In the hadoop cluster, the actual data is HDFS is Java based file system that provides reliable, scalable and a distributed way of storing application data into different nodes. For the sake of simplicity we will only consider the two major components of Hadoop i.e. Hadoop does a lot more than what is described Of large data sets accross clusters of computers using simple programming models.

Installing any of these components, let us first understand what these components are and what are they used for.Īpache Hadoop is software framework which is used to perform distributed processing

But my machines 4GB RAM seems tiny for that mammoth application to run and my system hanged!! I have to get this working for my project related stuff, looking forward for sincere help.In this blog, I will be demonstating how to setup single node Hadoop cluster using Docker on Mac os X. I have even tried the HortonWorks Sandbox for Apache Hadoop. Every other tutorial refers to a different directory to use, the one that got me Hadoop installed never mentions a bit about how to test a sample Hadoop map reduce application. Now how do I know which ones for which purpose.

Now all three directories have some subdirectory by name Hadoop and many other subdirectories like lib, lib exec.

Currently in my /usr/local/ there are 3 directories named hadoop-2.4.1, hadoop(a symlink to this i suppose) and a directory named Cellar.

Now I have Eclipse Luna installed but the guide I followed for illustrating "How to integrate Eclipse with Hadoop" tells me to import all the jars from './libexec' but for Hadoop 2.4.1 there are no jars, at least none that i could find.

I thought about checking whether Hadoop is correctly installed by running a sample program(WordCount.java) as is provided everywhere on the net.

Typing hadoop version shows 2.4.1 but running start-all.sh shows a long list of warnings.

I am not sure whether Hadoop is actually "correctly" installed.

I followed a tutorial for installing and currently my issues are these: I am having a real hard time installing Apache Hadoop(2.4.1) on my Mac(OS 10.9).Is there any step to step guide that fully explains and more importantly gets Hadoop running on my machine?.
