Ambud Sharma updated SPARK-21378:
---------------------------------
Description:
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.
https://github.com/apache/spark/blob/39e2bad6a866d27c3ca594d15e574a1da3ee84cc/external/kafka-0-10/src/main/scala/org/apache/spark/streaming/kafka010/CachedKafkaConsumer.scala#L75
This solution: https://issues.apache.org/jira/browse/SPARK-19275 keeps getting
"Added jobs for time" and eventually leads to "Failed to get records for
spark-xxxxx after polling for 3000"; in this case batch size is 3seconds
We can increase it to an even bigger number which leads to OOM.
