Sorry message sent as incomplete.
To better debug the issue, please check the below config properties:
- At Kafka consumer properties
- max.partition.fetch.bytes within spark kafka consumer. If not set
for consumer then the global config at broker level.
- request.timeout.ms
- At spark's configurations
- spark.streaming.kafka.consumer.poll.ms
- spark.network.timeout (If the above is not set, then poll.ms is
default to spark.network.timeout)
Generally I have faced this issue if spark.streaming.kafka.consumer.poll.ms is
less than request.timeout.ms
Also, what is the average kafka record message size in bytes?
