> The callBack Runnable may run after runOnNextHeartbeat but before wait(), if
> that happens, it will wait forever.
> So I think the wait() must set timeout.
> CommitterEventHandler#waitForValidCommitWindow
> while (now - lastHeartbeatTime > commitWindowMs) {
> rmHeartbeatHandler.runOnNextHeartbeat(new Runnable() {
> @Override
> public void run() {
> synchronized (EventProcessor.this) {
> EventProcessor.this.notify();
> }
> }
> });
> wait();
> lastHeartbeatTime = rmHeartbeatHandler.getLastHeartbeatTime();
> now = context.getClock().getTime();
> }
