----------------------------------
Summary: Streams get stuck in `PENDING_SHUTDOWN` is underlying
topics deleted.
Key: KAFKA-9416
URL: https://issues.apache.org/jira/browse/KAFKA-9416
Project: Kafka
Issue Type: Bug
Components: streams
Affects Versions: 2.4.0
Reporter: Andy Coates
We've noticed that if topics are deleted from under a running topology, e.g.
repartition, changelog or sink topics, then the stream threads transition from
`RUNNING` to `PENDING_SHUTDOWN`, but then do not transition to `ERROR`.
Likewise, if a Kafka cluster has auto topic create disabled and a topology is
started where its sink topic(s) do not exist, then the topology similarly gets
stuck in `PENDING_SHUTDOWN`.
Once the query is stuck in `PENDING_SHUTDOWN` any call to close the topology
blocks, as per https://issues.apache.org/jira/browse/KAFKA-9398.
We would like to see Kafka Streams handle this case and correctly transition to
`ERROR` state.
The cause of this is covered in more detail here:
