Can I do that with s3distcp / distcp? The job is being configured in the
run() method of s3distcp (as it implements Tool). So I think I can't use
this approach. I use this for the jobs I control of course, but the problem
is things like distcp where I don't control the configuration.

You try like below instead of runJob() you can try submitJob().
JobClient jc = new JobClient(job);

I'm submitting unrelated jobs programmatically (using AWS EMR) so they run
I'd like to run an s3distcp job in parallel as well, but the interface to
that job is a Tool, e.g. ToolRunner.run(...).
ToolRunner blocks until the job completes though, so presumably I'd need to
create a thread pool to run these jobs in parallel.
But creating multiple threads to submit concurrent jobs via ToolRunner,
blocking on the jobs completion, just feels improper. Is there an
