- These instructions are for installing and running Hadoop on a OS X single node cluster (Mac
Pro). This tutorial follows the same format and largely the same steps of the incredibly thorough
and well-written tutorial by <a href="http://www.michael-noll.com/wiki/Running_Hadoop_On_Ubuntu_Linux_(Single-Node_Cluster)"
target=_blank>Michael Noll</a> about Ubuntu cluster setup. This is pretty much his
procedure with changes made for OS X users. I also added other things that I was able to piece
together after looking up things from the <a href="http://hadoop.apache.org/core/docs/r0.17.2/quickstart.html"
target=_blank>Hadoop Quickstart</a> and the <a href="http://www.nabble.com/Hadoop-lucene-users-f17067.html">forums/archives</a>.
