## What changes were proposed in this pull request? [HDDS-12233](https://issues.apache.org/jira/browse/HDDS-12233) will help to improve the atomicity of container import. Revisit DiskBalancerTask#call to see if the flow can be improved accordingly. **Proposed Improvement -** 1. Copy Container: The existing logic to copy the container to a temporary directory on the destination disk remains the same. This corresponds to Step 1 `(Temp C1-CLOSED)`. 2. Transition to RECOVERING: Before moving the container to its final location, modify its .container file in the temporary directory to change its state from `CLOSED `to `RECOVERING`. This corresponds to Step 2 `(Temp C1-RECOVERING)`. 3. Move and Import: Move the container (now in a RECOVERING state) to its final directory and use the existing import logic. The Datanode will now see this container as RECOVERING. This corresponds to Step 3 (`C1-RECOVERING`). 4. Finalize to CLOSED: After the container is successfully imported and registered in the ContainerSet, do final state transition to change it from `RECOVERING` back to `CLOSED`. This corresponds to Step 4 (C1-CLOSED). 5. Delete Original: The original container on the source disk is deleted, as before. This corresponds to Steps 5 and 6. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-12434 ## How was this patch tested?
