Kafka 09 consumer does not commit offsets

[Renjie Liu]

Hi, all:
I'm using flink 1.1.3 and kafka consumer 09. I read its code and it says
that the kafka consumer will turn on auto offset commit if checkpoint is
not enabled. I've turned off checkpoint and it seems that kafka client is
not committing to offsets to kafka? The offset is important for helping us
monitoring. Anyone has encountered this before?
