Hive is only traditionally run on the Master node.
Hive creates a MapReduce task that is then executed by the cluster. Hive does not actually do distributed work. It simply translates requests into jobs, submits the jobs, then handles the results.
This is different to Apache Spark, which actually has executors on slave nodes too.
