> In yarn-client mode, client is deployed out side of cluster. When the net between client and cluster is broken, driver will be hanged. In this situation, user do not know   whether app is ok.
> So,  when no execuor send heartbeats to driver, We should close sparkContext. Let user know  app fails,  not only hangs driver
