Review comment:
Well in that case and if we keep the existing perf drivers (which it
might make sense in the short term) it might be better to rename also the test
class (e.g., `TestTezCustomTPCDSCliDriver`) to better reflect what we are
really testing.

> The existing regression tests (HIVE-12586) based on TPC-DS have certain
> shortcomings:
> The table statistics do not reflect cardinalities from a specific TPC-DS
> scale factor (SF). Some tables are from a 30TB dataset, others from 200GB
> dataset, and others from a 3GB dataset. This mix leads to plans that may
> never appear when using an actual TPC-DS dataset.
> The existing statistics do not contain information about partitions something
> that can have a big impact on the resulting plans.
> The existing regression tests rely on more or less on the default
> configuration (hive-site.xml). In real-life scenarios though some of the
> configurations differ and may impact the choices of the optimizer.
> This issue aims to address the above shortcomings by using a curated
> TPCDS30TB metastore dump along with some custom hive configurations.
