I don't quite understand the issue. Currently, the name should exactly
match the hash to make sure that each library is stored only once. Adding a
random suffix exactly destroys that behavior.
In the case where multiple clients upload the same jar to *different*
clusters, it should not be a problem, if they use different storage directories
(which they should definitely do).
In the case where multiple clients upload the same jar to the *same*
cluster, the first rename from tmp to file will succeed. The second rename from
tmp to file will fail, but that's not a problem, because the file already
exists with the same contents, and the client can assume success.
