Sort of.
You can’t use the actual MapReduce framework – the architecture is too incompatible with AppEngine.
However, there is an equivalent system built specficially for GAE – appengine-mapreduce. That site is a bit confusing, as the first version of the code only supported mappers, without the subsequent reduce step – recently they released a version with full mapreduce support, but some of the documentation still referes to the earlier mapper-only one.
The best introduction is the GoogleIO talk from Mike Aizatskyi.
