Can we randomly choose some subset of the tests (25% of total, for example)
to run for each cell in the test matrix?

I'd suggest we do a rolling pre-commit test runs among the testing
variables: hadoop1, hadoop2, vectorization on/off, tez, spark, etc. This
way, we still have coverage on all areas with a slight bigger latency of
issue discovery. Nevertheless, I think it's better to a fixed selection of
the variables.
