The move makes sense. Cloudera has cash on board and Hortonworks has excellent technical chops and associated vision. The offering is not Hadoop only. Druid can be deployed with ease and Superset can hook into it nicely, all with proper metrics captured. Ambari is a wonderful single pane of glass to manage it all nicely. YARN is really good at managing capacity leveraging cgroups. Spark is one thing but far from the only thing. E.g.Flink. Hadoop3 introduces Docker containers right into YARN. It is all driven with JVM components, so security actually works. For all its limitations HDFS also has pretty cool powers. HBase is also a beast for a couple use cases. It is a versatile platform and is evolving well. Of course the learning curve is pretty steep. But payoffs are huge.
