> Currently in HoS, in SparkClientImpl it first launch a remote Driver process, and then wait for it to connect back to the HS2. However, in certain situations (for instance, permission issue), the remote process may fail and exit with error code. In this situation, the HS2 process will still wait for the process to connect, and wait for a full timeout period before it throws the exception.
> What makes it worth, user may need to wait for two timeout periods: one for the SparkSetReducerParallelism, and another for the actual Spark job. This could be very annoying.
> We should cancel the timeout task once we found out that the process has failed, and set the promise as failed.
