nifi repository encrypt
Hallo all,
I have installed a 3 modes cluster with following specifications:
Nodes: milnifi[1,2,3]
OS: Red Hat Enterprise Linux Server release 7.8
Java: oracle 1.8.0_231
Nifi: 1.12.1
https port (9443) and nifi.cluster.protocol.is.secure are enabled and jks keystores are made by hand (no toolkit).
I use default ports for other services: nifi.cluster.node.protocol.port=11443, nifi.cluster.load.balance.port=6342.
Sensitive ops in configuration and flow.xml.gz are encrypted (by encrypt-config.sh) and repositories (flow, provenance, content) are encrypted too, with static key, for all nodes.
I simply follow the guide
This configuration looks like to works fine, but when I enable round rubin load balance in a processor (listFile for example) I see a lot of exceptions in nifi-app.log file:

************************************
Do I need some specific configuration inside processors?
In user documentation I see this configuration is marked as experimental, but can anyone help me try to debug (and solve if it's possible) or let me know if I made some mistakes during setup.
Sorry for my bad English ☹
Thanks in advance for any help.
With regards.
