emrCounter is a dead-simple python app that aims to illustrate the amount of work being done by a set of Amazon Elastic MapReduce (EMR) jobs running under a given AWS account. The jobs themselves log metrics to Amazon SimpleDB, and the emrCounter app serves up a page that shows an animated view of those metrics.
