Description

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 ran 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:
