dengkai updated FLUME-3043:
---------------------------
Description:
When we send a event with SinkCallback to kafka under DEBUG level of log4j, if
kafka reponses a result with exception but not a RecordMetadata. Kafka Sink
will throw NPE.
code in SinkCallback:
if (logger.isDebugEnabled()) {
long eventElapsedTime = System.currentTimeMillis() - startTime;
logger.debug("Acked message partition:{} ofset:{}", metadata.partition(),
metadata.offset());
logger.debug("Elapsed time for send: {}", eventElapsedTime);
}
code in Kafka Producer:
if (exception == null) {
RecordMetadata metadata = new RecordMetadata(...);
thunk.callback.onCompletion(metadata, null);
} else {
thunk.callback.onCompletion(null, exception);
}
