> Found these with [~rohithsharma] while browsing the code
> - In stop: it calls shutdownNow which doens't wait for pending tasks, should it use shutdown
instead ?
> {code}
>     public void stop() {
>       LOG.info("Stopping TimelineClient.");
>       executor.shutdownNow();
>       try {
>         executor.awaitTermination(DRAIN_TIME_PERIOD, TimeUnit.MILLISECONDS);
>       } catch (InterruptedException e) {
> {code}
> - In TimelineClientImpl#createRunnable:
> If any exception happens when publish one entity (publishWithoutBlockingOnQueue), the
thread exists. I think it should try best effort to continue publishing the timeline entities,
one failure should not cause all followup entities not published.
