>          Issue Type: Bug
>          Components: Streaming
>    Affects Versions: 1.6.0
>         Environment: Ubuntu 64bit, Intel i7
>            Reporter: Rado Buransky
>            Priority: Minor

> I am running Kafka server locally with extremely low retention of 3 seconds and with 1 second segmentation. I create direct Kafka stream with auto.offset.reset = smallest. 
> In case of bad luck (happens actually quite often in my case) the smallest offset retrieved druing stream initialization doesn't already exists when streaming actually starts.
> Complete source code of the Spark Streaming application is here:
> https://github.com/pygmalios/spark-checkpoint-experience/blob/cb27ab83b7a29e619386b56e68a755d7bd73fc46/src/main/scala/com/pygmalios/sparkCheckpointExperience/spark/SparkApp.scala
> The application ends in an endless loop trying to get that non-existing offset and has to be killed. Check attached logs from Spark and also from Kafka server.
