NiFi 1.2.0
I am having a custom processor and I wish to have a dedicated log file for the same. Accordingly, I have configured the com.datalake.processors.SQLServerCDCProcessor class to use an appender named 'SQLSERVER-CDC'
Following is the logback.xml :

</configuration>The strange fact is that the custom processor debug statements are written to both 'nifi-app.log' and the 'sqlserver-cdc.log' but I want these statements to be written only in the latter('sqlserver-cdc.log').
What am I missing ?
