> 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.
