-------------------------------------

             Summary: Kafka directInputStream logs what appear to be incorrect 
warnings
                 Key: SPARK-6569
                 URL: https://issues.apache.org/jira/browse/SPARK-6569
             Project: Spark
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.3.0
         Environment: Spark 1.3.0
            Reporter: Platon Potapov
            Priority: Minor


During what appears to be normal operation of streaming from a Kafka topic, the 
following log records are observed, logged periodically:

[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

* the "${part.fromOffset}" is not correctly substituted to a value
* is the condition really mandates a warning logged?
