> Remote spark client communicate with remote spark context asynchronously, if error/exception
is throw out during job execution in remote spark context, it would be wrapped and send back
to remote spark client, but if error/exception is throw out beyond job execution, such as
job serialized failed, remote spark client would never know what's going on in remote spark
context, and it would hangs there.
> Set a timeout in remote spark client side may not a great idea, as we are not sure how
long the query executed in spark cluster. we need find a way to check whether job has failed(whole
life cycle) in remote spark context.
