Ethan Rose commented on HDDS-8140:
----------------------------------
Based on container inspector output obtained later, it looks like the
containers reported in these log messages were deleted.
> 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
> Priority: Major
>
> 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}}|https://github.com/apache/ozone/blob/7f22916889b7bf39cdb31e5943cae5768f368198/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/transport/server/ratis/ContainerStateMachine.java#L279]
> that says there will be a race if container delete does not go through
> Ratis. When container 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.
