Description

It seems that the Kafka Consumer (0.8) fails to restart a job after it failed due to a Kafka broker shutdown.

java.lang.Exception: Unable to get last offset for partitions [FetchPartition {topic=a, partition=13, offset=-915623761776}, FetchPartition {topic=b, partition=13, offset=-915623761776}, FetchPartition {topic=c, partition=13, offset=-915623761776}, FetchPartition {topic=d, partition=13, offset=-915623761776}, FetchPartition {topic=e, partition=13, offset=-915623761776}, FetchPartition {topic=f, partition=13, offset=-915623761776}, FetchPartition {topic=g, partition=13, offset=-915623761776}].

I haven't understood the cause of this issue, but I'll investigate it.
