You could also try
1. Starting the main processing app as a process on the machines -and
leave it running-
2. have your mapper (somehow) talk to that running process, passing in
parameters (including local filesystem filenames) to read and write.
You can use RMI or other IPC mechanisms to talk to the long-lived process.
