User experience with any OpenSource software, especially in distributed computing and storing domain, depends on the quality of your system administrators and data engineering teams. If you couldn't connect software produced by different companies properly, it would be a pain to work with this software's zoo. Most people who used, for example, AWS stack don't want to return to OpenSource, because Amazon team tests interactions of their systems and uses properly config files which inexperienced system administrators can't. Additionally, you shouldn't use distributed storing systems if you can use horizontal sharding with SQL storing systems.
