MapReduce in C++

September 13, 2012 Leave a comment Go to comments

Since I can’t request the admistrator to configure any particular setting for the cluster nodes.  I found the simplest way is to compile your code locally, use hadoop streaming,  ship all you liked os-files with your mapper (compiled executable) together to the node. You could write a bash codes as the mapper, which config the lib-path, and wrap the exe inside it.  Below are some websites talking about MapReduce in C++, which actually very nice, but may need more to configure.

JavaCV : nice for using opencv  http://code.google.com/p/javacv/

Mapreduce-lit:  http://code.google.com/p/mapreduce-lite/

Very nice example(Mapper with Second key):  http://code.google.com/p/hadoop-stream-mapreduce/
