Ashish Kumar commented on HDDS-9095:
------------------------------------
No the abort is failing as entry in openKeyTable is missing. As in old
behaviour before this implementation only keys were getting deleted from
openKeyTable. So those orphan MPUs are existing in MultiPartInfoTable and
cannot be aborted.

> Cleanup expired incomplete MPUs

> Key: HDDS-9095
> URL: https://issues.apache.org/jira/browse/HDDS-9095
> Project: Apache Ozone
> Issue Type: Improvement
> Components: OM
> Reporter: Ivan Andika
> Assignee: Ivan Andika
> Priority: Major
> Fix For: 1.4.0
>
>
> In our cluster, there are around few thousands MPU keys in
> multipartInfoTable, with some of them being few months old.
> The reason is that these MPU keys are already initiated, and possibly
> committed few parts, but was not completed / aborted by the user. These
> spaces can be freed.
> Similar to the cleanup service OM open key table (HDDS-4120), we can
> implement clean up on MultipartInfoTable (and related open keys in
> OpenKeyTable) using a background job. -However, instead of using a new OM
> request / response, we can reuse the OM MPU abort request / response instead,
> which already handles the cleanup (i.e. expired inflight MPU can be aborted
> after a defined expiry threshold).-
>
> This is similar to {{AbortIncompleteMultipartUpload}} lifecycle
> configurations in AWS S3
> ([https://aws.amazon.com/blogs/aws-cloud-financial-management/discovering-and-deleting-incomplete-multipart-uploads-to-lower-amazon-s3-costs/]).
