>
> With Hive on Spark, users noticed that in certain cases
> spark.master=yarn-client offers 2x or 3x better performance than if
> spark.master=yarn-cluster. However, yarn-cluster is what we recommend and
> support. Thus, we should investigate and fix the problem. One of the such
> queries is TPC-H 22.
