             Summary: Support for Expression Language in Group ID field of 
Kafka Consumer Processors
                 Key: NIFI-5083
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
    Affects Versions: 1.6.0
            Reporter: Robert Bruno

I have the use case where I have two separate NiFi clusters reading data from 
the same topics but need to have unique group ids so they each get separate 
copies of the data.  It would be useful if the group id field supported 
expression language so I could use a processor group variable to define the 
group id to use.  I have a large enough number of kafka consumers to make this 
tedious to manually change.
