Resolution: Won't Fix
> Handle old clients not passing StoragePolicy in allocateBlock
> -------------------------------------------------------------

> Key: HDDS-17374
> URL: https://issues.apache.org/jira/browse/HDDS-17374
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Anurag Parvatikar
> Assignee: Anurag Parvatikar
> Priority: Major
> Labels: pull-request-available
>
> Handle old clients not passing StoragePolicy to OM in AllocateBlock: With an
> upgraded cluster containing all OMs supporting storagePolicy, an older client
> will not send the StoragePolicy field in any request made to the OM. This is
> of consequence to the allocateBlock as it allocates block based on the
> StoragePolicy sent by the client. If the client doesn't send a storage
> policy, it uses the bucket policy and falls back to the default.
> If the Key is created with the Bucket policy and before the subsequent
> allocateBlock call, the bucket policy changes, then allocateBlock would not
> stay true to the Key's StoragePolicy.
>
> This ticket is to handle such a scenario.
