One way we are currently doing this is: Expose limited set templates (those
will work with pre-defined sources and destinations) to users in a custom
portal, ask user specific configurations in the UI (custom) based on template
selection and integrate this UI with NiFi using REST.

It should work.

Until recently we were using nifi-1.6 nifi-hbase_1_1_2-client-service-nar

Hi,
Nifi version 1.7
We have a dataflow that would get data from Oracle database and load into hive
tables.
Data flow is something like below:

Hi Experts,
Any thoughts on how to make Hive processors (PutHiveStreaming, PutHiveQL etc.,)
to work with Hive 2.1.1 version. In nifi 1.7.x, hive bundle is compiled with
hive 1.2.1 version.
When I tried to compile with hive 1.2.1 (by updating pom file), lot compilation
issues. I tried to fix so
ks in your use-case, then I'd
recommend disabling "Use Avro Logical Types" at ExecuteSQL.
Thanks,

You mean, step:2 should be something like take flow.xml.gz from NiFi_Home/conf

The pattern for that example would be

The key part of that is the negative lookahead for ensuring it does
