I was going to ask if you had 2 jobs running. If the checkpointing for both are setup to look at the same location I could see an error like this happening. Do both spark jobs have a reference to a checkpointing dir?

OK I was running two spark streaming jobs, one using streaming data from Kafka and another from twitter in local mode on the same node. It is possible that the directory /user/hduser/checkpoint/temp is shared by both spark streaming jobs any experience on this please?
