>          Components: Streaming
>    Affects Versions: 1.3.0
>         Environment: Spark 1.3.0
>            Reporter: Platon Potapov

> {code}
> [Stage 391:==========================================>              (3 + 0) / 4]
> 2015-03-27 12:49:54 WARN KafkaRDD: Beginning offset ${part.fromOffset} is the same as ending offset skipping raw 0
> 2015-03-27 12:49:54 WARN KafkaRDD: Beginning offset ${part.fromOffset} is the same as ending offset skipping raw 0
> 2015-03-27 12:49:54 WARN KafkaRDD: Beginning offset ${part.fromOffset} is the same as ending offset skipping raw 0
> {code}
> * the part.fromOffset placeholder is not correctly substituted to a value
> * is the condition really mandates a warning being logged?
