How to create a Flowfile through HTTP nifi-api, Get the completion status of a flow.

New Contributor

Hi, In my use case, I want to use NiFi to transfer data from multiple source to multiple target. 

In this, we are scheduling a pipeline with multiple hops. One of these hops would be a NiFi Job to carry out the data transfer. 

Ex : Hop1 ---> Hop2----> Hop3 

 

Hop1 : Add data to Hadoop. 

Hop2 : Using NiFi read from Hadoop, Write to MySQL.

Hop3 : Run the required Job in MySQL.

 

I am interested in knowing 2 things here.

a. How to start the NiFi Process group through API.

Is there a way we can generate a flow file through a rest call? 

 

b. Know when the transfer process is completed. 

The trick here is that the NiFi cluster we are using is 3 node setup. How do we find the convergance/ completion of the flow.
