I'm running topology on storm which consume messages from kafka. Sometimes I encounter exceptions like offset out of range.  I did not pay much attention on this problem before and just restarted the topology to consume messages from latest offset because of various reasons. Recently, more services are dependent on kafka, and this problem still exists.  According to the invalid offset information, I did a test and finally found the problem. There exists an offset which consumer can never start from and can not skip over it unless you provide next valid offset to start from.  I can not figure out why.
