-------------------------------
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.
