> In SparkTask, we try to get job infos after the query finishes. Assume the job finishes
due to remote side crashes and thus closes the RPC. There's a race condition: if we try to
get job info before we notice the RPC is closed, the SparkTask waits for {{hive.spark.client.future.timeout}}
(default 60s) before it returns, even though we already know the job has failed.
