> Inaccurate numBlocksDeletion when getTransactions

> Key: HDDS-7125
> URL: https://issues.apache.org/jira/browse/HDDS-7125
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Xu Shao Hong
> Assignee: Xu Shao Hong
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.3.0
>
>
> Currently, we find that the deleted block txns in SCM RDB are not updated
> anymore.
> For the unhealthy container(no healthy replica and not enough replicas), SCM
> will not commit the txn and remove it from RDB until all desired replicas
> commit it. SCM will add the committed replica to the map
> `dnsWithTransactionCommitted`.
> In the process of `getTransactions`, SCM will read the txn out from RDB and
> try to add it to the result, but if the txn existed in the
> `dnsWithTransactionCommitted`, SCM will ignore it. No matter whether ignoring
> the txn, the numBlocksDeletion is still counting this, which will lead to
> nonsense running, and actually returning empty txns when the cluster has a
> certain amount of unhealthy containers.
