--------------------------------------
Summary: Ozone Bucket Support StoragePolicy and allowFallbackStoragePolicy
(was: Add bucket-level storagePolicy field on OmBucketInfo)
> Ozone Bucket Support StoragePolicy and allowFallbackStoragePolicy
> -----------------------------------------------------------------
>
> Key: HDDS-15872
> URL: https://issues.apache.org/jira/browse/HDDS-15872
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Devesh Kumar Singh
> Assignee: Devesh Kumar Singh
> Priority: Major
>
> Introduce a new optional storagePolicy field on OmBucketInfo and its
> BucketInfo protobuf representation. Values come from OzoneStoragePolicy (HOT,
> WARM, COLD). When set, this new field is the effective storage policy for the
> bucket. When unset, the existing deprecated BucketInfo.storageType field
> remains the source of truth for backward-compat, matching Ozone's convention
> of keeping old deprecated fields intact until an explicit removal migration.
> The field must be gated by the STORAGE_POLICY OM layout feature so a
> pre-upgrade OM cannot see or emit the field.
> {code:java}
> ozone sh bucket info
> {code}
> output must show both the new storagePolicy (when set) and the old
> storageType, with storagePolicy labeled as authoritative and storageType
> labeled (legacy) when both are set.
