[Premarajan, Ajay]

Hi Team,

We are currently using NiFi version 1.26 in our production environment. Is 
there a scheduled timeline for the major release of NiFi 2.0.0, or an estimate 
of how many milestone releases are planned before the major version is released?

RE: Nifi flow json to MiNifi flow json 2.0.0.M2 NIFI-12644

[Premarajan, Ajay]

Hi Team,

The nifi flow files when downloaded does not contain sensitive property 
information.
https://issues.apache.org/jira/browse/NIFI-12644 was addressed to convert nifi 
flow json to Minifi flow json. Since the sensitive properties are not present 
in the nifi flow files, we have to add it manually before starting MiNifi.

What is the way to handle this scenario, will senstivie properties be added to 
the Nifi flow files when downloaded or is there any approach for this?

I am enquiring this because we are doing an integration of MiNifi for internal 
project. I would be happy to contribute for the solution.

Kind Regard,
Ajay Premarajan

Subject: Nifi flow json to MiNifi flow json 2.0.0.M2

Hi Team,

I have a doubt regarding importing Nifi json flow to MiNifi json flow.
I am using code from https://github.com/apache/nifi/pull/8393 which was used 
resolve https://issues.apache.org/jira/browse/NIFI-12644 issue.

I have noticed that sensitive properties are not present when nifi flow json is 
downloaded. How are these values passed to MiNifi for operation.

For  ex:
I have an InvokeHttp processor which uses SSL controller and has the attribute 
“Request Username” and “Request Password” configured. When I download the Nifi 
Flow json, the “Request Password” field is missing. Plus the SSL controller 
donot have the password information in them.

this is causing problem when I try to convert the Nifi flow json into MiNifi 
flow json using the pull request code.

Please suggest an way forward.


Regards,
Ajay Premarajan

Re: Major bug in Apache NiFi 2.0.0-M2/2.0.0-M1

[Premarajan, Ajay]

Hi Team,

I have created a pull request to address this issue by adding a new method 
"transform" in minifi toolkit to convert json flow file from Nifi to MiNifi 
flow json file.
I have also updated the issue in JIRA to my name.
