Summary: Add upgrade handling to S3Multipart requests
Key: HDDS-14665
URL: https://issues.apache.org/jira/browse/HDDS-14665
Project: Apache Ozone
Issue Type: Sub-task
Reporter: Abhishek Pal
Assignee: Abhishek Pal
If we introduce a new schema, new writes may happen while we are in
pre-finalize state.
This means client might start writing with new schema version. But what happens
if they want to downgrade from that point?
So we need to add checks such that if the upgrade finalization has not been
done i.e. layout version still doesn't support the split table functionality,
new writes should be enforced with *schemaVersion: 0*.
Similar checks must be added to other requests where if any existing write is
happening with schemaVersion: 1 and the layout version doesn't support split
table, then we must throw error.
