How about handling the temp directory similar to the IOManager and
BlobManager: We create directory in the temporary directory (with a random
name) and use a shutdown hook to remove the directory on shutdown again.
I don't like keeping the jar files because it will pollute the directory on
the server.
Also the current approach does not allow running multiple JobManagers at
the same machine (something that can easily happen with YARN).
