+        CancellableCleanerCallable queryCleanerTask = pendingQueryCleanerTasks.get(queryIdentifier);
+        if (queryCleanerTask != null) {
+          boolean cancelled = queryCleanerTask.cancel();
+          if (!cancelled) {
+            throw new IOException("Unable to cancel pending query cleanup for " + queryIdentifier);
{noformat}
