Chesnay Schepler commented on FLINK-16714:
------------------------------------------
A negative value means that the offset was not fetched yet from Kafka yet; any
non-negative value would be misleading as they may denote a valid kafka offset.
> Kafka committedOffsets value <0

> dear all:
> use rest api get kafka offsets sometimes produces errors value like <
> 0, so use this value monitoring Kafka's lag size will produce false
> positives. This should be the problem of flink metrics collection?
