-------------------------------------
Summary: NullPointerException when communication issue with kafka
server
Key: FLUME-3064
URL: https://issues.apache.org/jira/browse/FLUME-3064
Project: Flume
Issue Type: Bug
Components: Kafka Channel, Sinks+Sources
Affects Versions: v1.7.0
Environment: logging level must be DEBUG
Reporter: Laszlo Hornyak
Priority: Minor
When flume has communication issues with kafka and the logging level is set to
DEBUG, additionally to the log of the communication error an NPE will be
thrown. This happens because kafka callback metadata parameter [can be
null|https://kafka.apache.org/082/javadoc/org/apache/kafka/clients/producer/Callback.html#onCompletion(org.apache.kafka.clients.producer.RecordMetadata,%20java.lang.Exception)],
this is not handled, but it is only evaluated if the log level is DEBUG.
The problem affects the kafka source and the channel.
