["Supratim Deka (JIRA)" <ji...@apache.org>]

Supratim Deka resolved HDDS-1740.
---------------------------------
    Resolution: Not A Problem

On the Datanode, Container state changes are driven through

KeyValueContainer.updateContainerData()

 

this always resets the in-memory state of the container to the previous state in case the update to the container YAML hits any exception. Also, the container YAML is sync flushed to persistent storage as implemented in:

ContainerDataYAML.createContainerFile()

 

So I am marking this as not a problem.

> Ensure consistent state in-memory and in the persistent YAML file for the Container.
> If an update to the YAML fails, then the in-memory state also does not change.
> This ensures that in every container report, the SCM continues to see the specific container is still in the old state. And this triggers a retry of the state change operation from the SCM.
