--------------------------------
Summary: Startup warning about adding containers to missing
container set
Key: HDDS-8140
URL: https://issues.apache.org/jira/browse/HDDS-8140
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Ethan Rose
This message was observed in the logs on startup for 250 containers. The same
message occurred on 3/6 datanodes for the same set of containers on each node:
{code}
2023-02-16 16:43:05,799 WARN
org.apache.hadoop.ozone.container.common.impl.ContainerSet: Adding container
64079 to missing container set.
{code}
This is a byproduct of HDDS-935, which is an old and involved change. In that
change there is a TODO in {{ContainerStateMachine#persistContainerSet}} that
says there will be a race if block delete does not go through Ratis. When block
deletion was implemented after that change, it did not go through Ratis so the
race may happen. We need to revisit this area of the code.
