In the ConsumerStrategy class there is a pause on the consumer. We never resume the consumer and that seems to causing the issue. The KafkaConsumer implementation has changed between 10.0.1 and 10.1.0 which has exposed this issue. The solution to this issue is to resume the consumer before we find the position in DirectKafkaInputDStream class in the latestOffsets method. I have tested this fix and it works fine. The reason the issue is not seen in the current setup is because pause/resume logic is changed in the latest kafka version. We dont seem to have a resume for the pause and hence this fix is necessary.

What changes were proposed in this pull request?
This pull request is to fix for SPARK-18779. When using kafka 0.10.1.0 messages are being read only from one partition. The current kafka-spark 0.10 integration ships with kafka 0.10.0.1 where messages are read from all partitions but using kafka client 0.10.1.0 client, messages are read from only one partition.
In the ConsumerStrategy class there is a pause on the consumer. We never resume the consumer and that seems to causing the issue. The KafkaConsumer implementation has changed between 10.0.1 and 10.1.0 which has exposed this issue. The solution to this issue is to resume the consumer before we find the position in DirectKafkaInputDStream class in the latestOffsets method.The reason the issue is not seen in the current setup is because pause/resume logic is changed in the latest kafka version. We dont seem to have a resume for the pause and hence this fix is necessary.
This patch fixes the issue.
How was this patch tested?
The spark-kafka test cases were run to check no regressions were caused. I have checked that messages are being read from all partitions for both 0.10.0.1 kafka client and 0.10.1.0 client.
