Hey ! A key would be nice <| sep |> Speak for yourself . For those who don ' t get the reference <| sep |> They ' re probably not very good or up to date in their field . You keep saying this but why does it mean that ' s ' probable '? You don ' t even know these people and what companyprojectsexperience they have . And this is purely based on how they pronounce ' SQL '. I could play devil ' s advocate here , and say it could be down to how ' newbies ' in a loose sense are pronouncing it and they unconsciously latch onto that term . Either way , it doesn ' t mean they are shit at their job . What you learn in a classroom is understandably lacking functional experience . Who said it wasn ' t ? But someone who has been working for decades in the field and continues to fail to get the simple memo is not authoritative . What is the simple memo and why is it relevant to their expertise ? Like I said , even in my world of hadoop I deal with SQL . Chances are your veterans would shit their pants in hadoop . Another baseless assertion . btw , we have products that plug into Hadoop though I personally haven ' t used them
