--------------------------------------
Summary: Use timeout when joining threads in system test services
Key: KAFKA-3581
URL: https://issues.apache.org/jira/browse/KAFKA-3581
Project: Kafka
Issue Type: Bug
Components: system tests
Reporter: Jason Gustafson
Assignee: Jason Gustafson
We have several instances in our system test services where we invoke
Thread.join() in the stop_node() function to stop the service. It probably
makes sense to use a timeout in join() to ensure that the process eventually
has a chance to do unclean shutdown when the process becomes unresponsive. We
have seen several cases in our daily runs (with the verifiable consumer in
particular) where the process seems to hang on this join.
