Solution 1
You topic name is not valid because it has character '?' which is not legalCharacter for topic names.
Solution 2
I got same error. in my case problem was space between comma separated topics in my code:
@source(type='kafka',
topic.list="p1, p2, p3",
partition.no.list='0',
threading.option='single.thread',
group.id="group",
bootstrap.servers='kafka:9092',
@map(type='json')
)
finally find solution:
@source(type='kafka',
topic.list="p1,p2,p3",
partition.no.list='0',
threading.option='single.thread',
group.id="group",
bootstrap.servers='kafka:9092',
@map(type='json')
)

when I run the following command with kafka 0.9.0.1 i get this warnings[1]. Can you please tell me what is wrong with my topics? (I'm talking to the kafka broker which runs in ec2)
#./kafka-console-consumer.sh --new-consumer --bootstrap-server kafka.xx.com:9092 --topic MY_TOPIC?
