Major Description
When using the kafka.tools.ConsumerOffsetChecker to check offsets for consumers that are doing manual offset management, and offsets for some but not all partitions have been stored, the offset checker will throw a no node exception. It should probably return 0 for partitions that dont have an offset recorded yet.
In this case I was using github.com/pinterest/secor, which may read thousands or millions of messages from a partition before committing an offset.
