NiFi -- Help


Can anyone help in solving the following error

I am trying to import data from mysql to hive



Super Guru

Can you share your configuration of QueryDatabaseTable and its DBCP Controller Service? Also you should be able to find more information about those bulletins/errors in logs/nifi-app.log, please paste in the relevant stack trace as it will help determine the issue you're having.


Hey @Nikhil Vemula!
I'm not sure about your error, but are you able to connect to the mysql from your Nifi host?

telnet <mysql> port

And could you share your configs from querydatabse processor and see if there's more detail on nifi's log.
PS: Did you set any DBCPConnectionPool at the controller service?

Hope this helps!
