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.

Update Scala, Java and Python examples of Direct Kafka word count to access the

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
