https://cwiki.apache.org/confluence/display/AMBARI/Installation+Guide+for+Ambari+2.7.5 was updated in December. It isn't a completely dead project. I saw in a video that there was a click-button to connect #Kafka to #Hadoop, so I thought I would check it out. We support Kafka and Hadoop, but not #Ambari. We were asked to, but declined.
Hadoop is not really a priority these days, but Kafka is.
The entire time I have been typing this, maven has been pulling down dependencies...
