[jira] [Created] (HDDS-3719) Datanode may fail to stop
Attila Doroszlai created HDDS-3719:
--------------------------------------
Summary: Datanode may fail to stop
Key: HDDS-3719
URL: https://issues.apache.org/jira/browse/HDDS-3719
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Datanode
Reporter: Attila Doroszlai
TestOzoneManagerListVolumes timed out after 2 minutes while trying to stop the mini cluster. It seems one of the datanodes was stuck in an infinite loop trying to execute a task on a terminated executor:
