Hi all,
I'm building a Spark Streaming application that will continuously read
multiple kafka topics at the same time. However, I found a weird issue that
it reads only hundreds of messages then it stopped reading any more. If I
changed the three topic to only one topic, then it is fine and it will
continue to consume. Below is the code I have.
val consumerThreadsPerInputDstream = 1
val topics = Map("raw_0" -> consumerThreadsPerInputDstream)
"raw_1" -> consumerThreadsPerInputDstream,
"raw_2" -> consumerThreadsPerInputDstream)
val msgs = KafkaUtils.createStream(ssc, "10.10.10.10:2181/hkafka",
"group01", topics).map(_._2)
.......
How come it will no longer consume after hundreds of messages for three
topic reading? How to resolve this issue?
Thank you for your help,
Eason
