bartektartanus opened a new pull request #3885: NIFI-6836 Increased topic list length in ConsumeKafka and added validator
URL: https://github.com/apache/nifi/pull/3885
 
 
   #### Description of PR
   
   NIFI-6836 - this PR increases the topic length limit from 100 to 1000 and also adds validator to warn the user about it. 
   
   I've submitted this issue few days ago and prepared initial version of PR - fixed only for `KafkaConsumer1_0`. This bug is in every Kafka Consumer, from 0_10 to 2_0. I can also make changes in all files, but maybe some refactoring should be done? Some `AbstractKafkaConsumer` with all common properties? Or maybe current approach is intended as you do want to mix code between different versions of Kafka Consumer?
