Unlike Map Reduce which is not used much now, what components from hadoop are still used a lot today

[Monica Shiralkar]

Around a decade back,Hadoop was the most popular way for processing Big Data. Oflate, the popularity of map reduce became less with Spark/Flink/Strom giving better performance and more options. Which components of Hadoop ecosystem are used the most these days. I understand it is not map reduce but I think Hive is one which is being used a lot for ad hoc analysis. Not sure about how much HBase is being used these days.

Thanks.
