             Summary: GetKafka cannot handle null value in Kafka offset cause NullPointerException
                 Key: NIFI-2903
                 URL: https://issues.apache.org/jira/browse/NIFI-2903
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 0.7.0, 1.0.0
            Reporter: Kurt Hung


The GetKafka processor does not handle the condition of null value that exists in Kafka offset, which would cause the processor hang on and generate a NullPointerException after 30 sec. It's easy to reproduce this issue; I use the kafka-python to insert a key-value pair ("abc", None), and create a GetKafka processor to consume the topic I've created. This issue would happen immediately, and moreover, the processor could't consume rest offsets.

Temporary I customize a GetKafka processor for a "Failure" relationship to handle null values exist in Kafka offset to prevent this issue.
