We're using Kafka 0.8.2 and are puzzled by the offset behaviour when
they are stored in kafka topics.
Upon restart of the Kafka cluster (e.g. due to reconfiguration) it can
happen that the offsets are unknown and therefore stop consumers from
consuming without knowing their offset.
kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --group group
--zookeeper localhost:2181
Could not fetch offset for [topic,19] due to
kafka.common.OffsetsLoadInProgressException.
Group Topic Pid Offset
logSize Lag Owner
group topic 0 unknown 326606 unknown none
I currently have no other solution to this than to wait.. but it takes a
very long time (hours.. the servers are hopelessly underutilized!), I
would be grateful for any advice.
Thanks
Jörg
