> In HoS, after a RemoteDriver is launched, it may fail to initialize a Spark
> context and thus the ApplicationMaster will die eventually. In this case,
> there are two issues related to RemoteSparkJobStatus::getAppID():
> 1. Currently we call {{getAppID()}} before starting the monitoring job. For
> the first, it will wait for {{hive.spark.client.future.timeout}}, and for the
> latter, it will wait for {{hive.spark.job.monitor.timeout}}. The error
> message for the latter treats the {{hive.spark.job.monitor.timeout}} as the
> time waiting for the job submission. However, this is inaccurate as it
> doesn't include {{hive.spark.client.future.timeout}}.
> 2. In case the RemoteDriver suddenly died, currently we still may wait
> hopelessly for the timeouts. This should potentially be avoided if we know
> that the channel has closed between the client and remote driver.
