Hive is only traditionally run on the Master node. Hive通常仅在主节点上运行。
Hive creates a MapReduce task that is then executed by the cluster. Hive创建一个MapReduce任务，然后由集群执行。 Hive does not actually do distributed work. Hive实际上并没有做分布式工作。 It simply translates requests into jobs, submits the jobs, then handles the results. 它只是将请求转换为作业，提交作业，然后处理结果。
This is different to Apache Spark, which actually has executors on slave nodes too. 这与Apache Spark不同，后者实际上在从属节点上也具有执行程序。
