Team, For the full time NiFi has been in Apache we've built with support for various Hadoop ecosystem components like HDFS, Hive, HBase, others, and more recently formats/serialization modes like necessary for Parquet, Orc, Iceberg, etc..
All of these things however present endless challenges with compatibility across different versions (Hive being the most difficult by far), vendors (hadoop vendors, cloud vendors, etc..). And also super notably the incredible number of dependencies, dependency conflicts, inclusions/exclusions, old log libs, vulnerability updates, etc.. And last but certainly not least a big reason why our build has grown so much. We have a couple options: 1. Deprecate these components in NiFi 1.x and drop them entirely in NiFi 2.x. Leave this as a problem for vendors to deal with. NiFi users interacting with such components are nearly exclusively doing so with vendors anyway. 2. Remove the components from NiFi main code line and create a separate repo for 'nifi-hadoop-extensions'. We manage those independently and release them periodically. They would be available for people to grab the nars if they want to use them. We include none of them in the convenience binary going forward by default. 3. Change nothing. Continue to battle with the above listed items. This is admittedly a bit of a non-option. We can't keep spending the same time/energy on these we have. It is a very small number of people that fight this battle. Look forward to hearing thoughts on these options or others we might consider. Thanks
