kafka-connect-hdfs offset out of range behaviour

2016-07-13 Thread Prabhu V
The kafka-connect-hdfs just hangs if the "offset" that it expects is no longer present (this happens when the message get deleted because of retention time) The process in this case does not write any output and the messages get ignored. Is this by design ? The relevant code is TopicPartitionWr
