Thanks for doing sanity & performance tests.
@cestella
Thanks for reviewing.
STORM-2994: Before the patch, KafkaSpout cannot commit `null tuple`, which
means it can still consume messages but doesn't commit offsets, and probably
eventually stuck.
I'll update the PR to include storm-kafka-client 1.2.2. Thanks again!---
