             Summary: Spark Poll timeout when specific offsets are passed
                 Key: SPARK-21378
                 URL: https://issues.apache.org/jira/browse/SPARK-21378
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.0.2, 2.0.0
            Reporter: Ambud Sharma


Kafka direct stream fails with poll timeout:

{code:java}
JavaInputDStream<ConsumerRecord<String, String>> stream = KafkaUtils.createDirectStream(ssc,
				LocationStrategies.PreferConsistent(),
				ConsumerStrategies.<String, String>Subscribe(topicsCollection, kafkaParams, fromOffsets));
{code}

Digging deeper shows that there's an assert statement such that if no records are returned (which is a valid case) then a failure will happen.

{code:java}
https://github.com/apache/spark/blob/39e2bad6a866d27c3ca594d15e574a1da3ee84cc/external/kafka-0-10/src/main/scala/org/apache/spark/streaming/kafka010/CachedKafkaConsumer.scala#L75
{code}
