> For a partitioned table, the class {{StatsNoJobTask}} is supposed to launch
> threads for all partitions and compute their stats. However, it could exit
> early after at most 100 seconds:
> {code}
> private void shutdownAndAwaitTermination(ExecutorService threadPool) {
> // Disable new tasks from being submitted
> threadPool.shutdown();
> try {
> // Wait a while for existing tasks to terminate
> if (!threadPool.awaitTermination(100, TimeUnit.SECONDS)) {
> // Cancel currently executing tasks
> threadPool.shutdownNow();
> // Wait a while for tasks to respond to being cancelled
> if (!threadPool.awaitTermination(100, TimeUnit.SECONDS)) {
> LOG.debug("Stats collection thread pool did not terminate");
> }
> }
> } catch (InterruptedException ie) {
> // Cancel again if current thread also interrupted
> threadPool.shutdownNow();
> // Preserve interrupt status
> Thread.currentThread().interrupt();
> }
> }
> {code}
> The {{shutdown}} call does not wait for all submitted tasks to complete, and
> the {{awaitTermination}} call waits at most 100 seconds.
