I am using HDP2.5 . I try to inject data into postgresql through Nifi. I attach my process here
When I start my Nifi flow, I got issue on " Data is replicate in postgresql". I just pass 5 records but it shows me 300 records in postgres database
Did you schedule your GetHTTP processor ? By default, it continually runs. So your data are continually fetched. You have to configure this property in the "Scheduling" tab.
An easy way, in test : keep the "Timer driven" strategy and set the Run Schedule with a big interval. So you can start your flow and stop it before the second execution.
Thanks Quentin T
