Subject Re: Resume checkpoint failed with Spark Streaming Kafka via createDirectStream under heavy reprocessing

I'd try logging the offsets for each message, see where problems start,
then try using the console consumer starting at those offsets and see if
you can reproduce the problem.

Streaming Kafka method createDirectStream, everything is fine till a driver error happened
(driver is killed, connection lost...). When the driver pops up again, it resumes the processing
with the checkpoint in HDFS. Except, I got this:
