Summary: kafka process should exit when it encounters
"java.io.IOException: Too many open files"
Key: KAFKA-6544
URL: https://issues.apache.org/jira/browse/KAFKA-6544
Project: Kafka
Issue Type: Bug
Components: admin, network
Affects Versions: 0.10.2.1
Reporter: Yu Yang
Our kafka cluster encountered a few disk/xfs failures in the cloud vm
instances. When a disk/xfs failure happens, kafka process did not exit
gracefully. Instead, it run into "<defunct>" status, with port 9092 still be
reachable. when failures like this happens, kafka should shutdown all threads
and exit. The following is the kafka logs when the failure happens:
