I remember when I was first setting up a hadoop cluster wondering exactly what the SSH-KEYs did and why and if they were needed. start-all.sh and stop-all.sh are good for what they do but they are not very sophisticated.
I wrote a blog about using func with hadoop to remotely manage your nodes. http://www.edwardcapriolo.com/roller/edwardcapriolo/entry/func_hadoop_the_end_of Warning: My blogs are not nicely polished like those of Lars George http://www.larsgeorge.com/2009/10/hbase-architecture-101-storage.html, (because I do not have a lot of time) but I hope the content is interesting to some. Thank you, Edward
