Hi,

What do you mean by "stuck"? What do the logs say? Is the Kafka spout still
running and re-emitting batches?

Could you try to revert Storm to use ZMQ transport instead of Netty (the
new default)? In my case, using Netty seems to block my topology
sometimes (like in your case, it's a Trident transactional Kafka topology
too), i.e. the spout is continuously re-emitting batches which never seem
to get ack-ed.
