----------------------------------
Summary: Change Cannot close container log message from WARN to
DEBUG
Key: HDDS-6059
URL: https://issues.apache.org/jira/browse/HDDS-6059
Project: Apache Ozone
Issue Type: Bug
Environment: This is likely what was happening:
# IN a pipeline DN send close container action to SCM when it reaches
container threshold 90% of container size.
# That triggers close container event, which moves container state to CLOSING
state in SCM, and send command to DN's to close
# Then DN moves to CLOSED State, then in next HB it sends DN replica state as
closed, and we move state of Container to CLOSED in SCM.
# But when other DN's in pipeline reach threshold, they will also fire similar
close container action, but as one DN reported closed we already moved to
CLOSED State in SCM, so that is reason for other close container event
handlers(triggered when follower DN reached threshold will trigger) and for
those we see already in closed state.
We can move this to DEBUG, like how we log for ContainerActions. At this point,
looks like this shall not cause a problem, further investigation is needed to
understand why this was happening.

When IncrementalContainerReportHandler move a container to close state, some
where else was firing a close container event to close the same container
causing a WARN log entry.
