I am using the GetMongo processor to query a mongoDB for a particular key value pair and if the data is found then I want to log that But if the data is not found in the DB then I want to use the same key value pair (already present in the attributes of each flow file) that is failed and input into the next processor how can I approach this issue.

I have created a three node NIFI cluster and the embedded zookeeper is set up and all the three nodes are communicating with each other through heartbeats but when I try to access the NIFI UI I am getting the below error: Unauthorized error="invalid_token", error_description="An error occurred while attempting to decode the Jwt: Signed JWT rejected: Another algorithm expected, or no matching key(s) found", error_uri="https://tools.ietf.org/html/rfc6750#section-3.1" How do I fix this issue?

I have to make a flow where I want to check that two Mongo DBs are in sync so everyday I have to compare the count of records that are being inserted into both the DBs if there is a discrepancy I want to transfer the records from the main DB to the DB which doesn't have it. Both DBs have a created AT key which has the date when the record was added. I want to achieve this through apache NIFI.

Embedded zookeeper is failing to start while setting up a three node cluster for NIFI. The error message indicates that there is an issue with starting the embedded Zookeeper server while starting NiFi on your three-node cluster. The specific error causing the problem is "Address already in use," which suggests that the port required by Zookeeper is already occupied by another process. How can I solve this issue?
