Summary: SCM to reject adding container to closed pipeline
Key: HDDS-7829
URL: https://issues.apache.org/jira/browse/HDDS-7829
Project: Apache Ozone
Issue Type: Bug
Reporter: Duong
This is a correction of the fix for "SCM terminates when adding containers to a
closed pipeline" in HDDS-7738.
In general, due to the lack of atomicity and the fact that SCM status can
change between transactions, SCM should define an expected precondition for
each transaction it processes and reject the transaction gracefully if the
condition is not met.
For example, when processing a transaction adding a container, SCM expects the
associated pipeline to be in an OPEN state and rejects the container creation
if the pipeline is CLOSED.
This ticket focuses on correcting HDDS-7738, but also builds the basic
exception handling in SCM Ratis's applyTraction to allow logical rejections.
