I think this is kind of mixed up. Data warehouses are simple SQL creatures; Spark is (also) a distributed compute framework. Kind of like comparing maybe a web server to Java. Are you thinking of Spark SQL? then I dunno sure you may well find it more complicated, but it's also just a data warehousey SQL surface.
But none of that relates to the question of data quality tools. You could use GE with Redshift, or indeed with Spark - are you familiar with it? It's probably one of the most common tools people use with Spark for this in fact. It's just a Python lib at heart and you can apply it with Spark, but _not_ with a data warehouse, so I'm not sure what you're getting at. Deequ is also commonly seen. It's actually built on Spark, so again, confused about this "use Redshift or Snowflake not Spark".
