Hello, I'm following the tutorials for HDF, but I'm struggling to do the "Real-Time Event Processing In NiFi, SAM, Schema Registry and SuperSet". I cannot find in the HDF virtualbox image the Druid and Superset that they use in the tutorial. When I try to add a new service in Ambari doesn't appear the options to install Druid or Superset. What I'm doing wrong? https://hortonworks.com/tutorial/real-time-event-processing-in-nifi-sam-schema-registry-and-superset/ Thank you, Rui ... View more

Hello Everyone, I'm want to copy all the content from a Hive table and tranform it to a JSON file, but must recurrently in order to copy new content that the Hive table could have. I managed to use the processor "SelectHiveQL" to extract the data. The problem is that I can't collect the data that was only created after the last collection of data.
