[jira] [Updated] (SPARK-9059) Update Python Direct Kafka Word count examples to show the use of HasOffsetRanges

     [ https://issues.apache.org/jira/browse/SPARK-9059?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Owen updated SPARK-9059:
-----------------------------
       Priority: Minor  (was: Major)
    Description: 
Update Python examples of Direct Kafka word count to access the offset ranges using HasOffsetRanges and print it. For example in Scala,
 
{code}
var offsetRanges: Array[OffsetRange] = _
...
directKafkaDStream.foreachRDD { rdd => 
    offsetRanges = rdd.asInstanceOf[HasOffsetRanges]  
}
...
transformedDStream.foreachRDD { rdd => 

    // some operation
    println("Processed ranges: " + offsetRanges)
}

{code}

See https://spark.apache.org/docs/latest/streaming-kafka-integration.html for more info, and the master source code for more updated information on python. 

  was:
Update Scala, Java and Python examples of Direct Kafka word count to access the offset ranges using HasOffsetRanges and print it. For example in Scala,
 
{code}
var offsetRanges: Array[OffsetRange] = _
...
directKafkaDStream.foreachRDD { rdd => 
    offsetRanges = rdd.asInstanceOf[HasOffsetRanges]  
}
...
transformedDStream.foreachRDD { rdd => 

    // some operation
    println("Processed ranges: " + offsetRanges)
}

{code}

        Summary: Update Python Direct Kafka Word count examples to show the use of HasOffsetRanges  (was: Update Direct Kafka Word count examples to show the use of HasOffsetRanges)

Updating this to be about Python only as the rest is seemingly covered in SPARK-8390 already
