Migrate to nifi standalone from HDF cluster - apache-nifi

Question

I'll comment on the problem i'm having.
In the company where I work, they decided a few years ago to implement nifi.
The problem with this is that they implemented the complete HDF solution, something really unnecessary to use only nifi.
With luck the Ambari interface is used to restart the service
I am currently in the process of migrating this nifi that consists of 3 clustered nodes (something also unnecessary since only small tasks are performed and resources are wasted) to a dockerized nifi standalone.
This process was done previously with a nifi with a smaller flow successfully.
The procedure that was carried out was simply to export a template of the flow and to import it, adding in the nifi.properties the correct keys to be able to use the controller services.
I find myself trying to perform this same procedure without success.
The flow is imported correctly but I can not visualize the controllers services that I have loaded by adding the correct key to the nifi.properties.
Try extracting the key from the controller services for load manually that appears as "sensitive value" but I could not do it.
As 2nd option copy the flow.xml.gz of the server to be migrated, edit some fields with a text editor (such as file paths, drivers, etc) and apparently I'm better with this;
I had several errors, among which I had to add the drivers (jdbc, hive, etc). I'm correcting small problems little by little.
Is there really any correct way to migrate this?
Because for more than correctly entering the password in the nifi.properties file, I can not see the controller services? Does HDF have any other configuration files?
As an extra data, the version of dockerized nifi used is 1.2.0, the version of nifi that currently has HDF is 1.1.0. Apparently there are no major changes that could affect.
Thanks for the help!

Answer 1

The sensitive properties in the flow.xml.gz file are encrypted with a key derived from nifi.sensitive.props.key entry in nifi.properties. If this value is itself encrypted (i.e. it is of the form abcdef...||abcdef...), you will also need to copy the nifi.bootstrap.sensitive.key value from bootstrap.conf. With those two values (and using the same algorithm for KDF and encryption as specified in nifi.sensitive.props.algorithm in nifi.properties), your new NiFi instance should be able to decrypt the sensitive processor properties that are embedded in an encrypted form in flow.xml.gz.

Answer 2

Thanks for the help
I did not know this about the master key in the bootstrap.conf file
I have done the following:
- Export from the original nifi the flow, and import it into the new nifi.
- Edit indicating the keys in the nifi.properties and bootstrap.conf
- The service does not start, the logs announce the following

After this it seems the service keeps restarting so replace the nifi-framework-nar file with version 1.1.0 so that it does not have the correct jasypt library. (Remember with i having migrate nifi 1.1 to 1.2)
Nifi keeps restarting announcing the following error.

Delete the folder of the flowfiles but it still does not start.
I did the test of using the folder lib of my nifi 1.1 and the error is the following one: Error: Could not find or load main class org.apache.nifi.bootstrap.RunNiFi
Where are the files specified to be used in nifi?
Apparently for more than amount the flow in the right way, the operation of the processors continues to depend on the files nar with the libraries belonging to its version.
Thanks!
