Wow! Check out these great slides from Aaron Cordova's talk about HadoopWorld!
http://www.cloudera.com/sites/all/themes/cloudera/static/hw09/3%20%20-%202-30%20Aaron%20Cordova,%20BAH,%20HadoopWorldComplete.pdf They clearly explain why you might want to use Tahoe-LAFS instead of HDFS to store the data that you are computing over with MapReduce. They also include some performance comparisons between Tahoe-LAFS and HDFS under MapReduce. Aaron: if you're reading this, could you give us more information about how Tahoe-LAFS gets used by MapReduce? The write performance was terrible.
