The latest version of IndexedRDD supports any key type with a defined serializer <https://github.com/amplab/spark-indexedrdd/blob/master/src/main/scala/edu/berkeley/cs/amplab/spark/indexedrdd/KeySerializer.scala>, including Strings. It's not released yet, but you can use it from the master branch if you're interested.
