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?. I followed a tutorial for installing and currently my issues are these:
- I am not sure whether Hadoop is actually "correctly" installed. Typing
hadoop versionshows 2.4.1 but running
start-all.shshows a long list of warnings.
- I thought about checking whether Hadoop is correctly installed by running a sample program(WordCount.java) as is provided everywhere on the net. 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.
- 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 all three directories have some subdirectory by name Hadoop and many other subdirectories like lib, lib exec. Now how do I know which ones for which purpose. 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.
I have even tried the HortonWorks Sandbox for Apache Hadoop. 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.
