How well do those work on a single 8GB node? Because ClickHouse works very well at that scale, with a single C++ executable. There's large complexity and cost overheads to Hadoop solutions, and not everyone has actual big data problems. ClickHouse hugely outperforms on query patterns that would devolve into table scans in a row store, while working at row store volumes of data without a bunch of big nodes.
