DelegationTokenRenewer uses a thread pool to manage token renewals. The number of threads is configurable, but unfortunately the pool never expands beyond the hardcoded initial 5 threads because we are using an unbounded LinkedBlockingQueue. ThreadPoolExecutor only grows the thread pool beyond the core size when the specified queue is full.
