> Issue Type: Improvement
> Components: SCM
> Affects Versions: 1.3.0
> Reporter: JiangHua Zhu

> When SCM issues repeated deleteblocks commands to DN, we will get the following information in the DN's log:
> {code:java}
> 2023-11-21 15:57:16,711 [BlockDeletingService#5] WARN org.apache.hadoop.ozone.container.keyvalue.KeyValueHandler: Missing delete block(Container = xxxx, Block = xxxxxx
> 2023-11-21 15:57:16,711 [BlockDeletingService#2] WARN org.apache.hadoop.ozone.container.keyvalue.KeyValueHandler: Missing delete block(Container = xxxx, Block = xxxxxx
> 2023-11-21 15:57:16,711 [BlockDeletingService#4] WARN org.apache.hadoop.ozone.container.keyvalue.KeyValueHandler: Missing delete block(Container = xxxx, Block = xxxxxx
> {code}
> This shouldn't happen because some block files have been deleted.
> There is a situation that will cause this phenomenon, that is, SCMBlockDeletingService has prepared the DeleteBlocksCommand set in advance, and the datanode has previously executed and deleted part of the block information. At this time, this batch of commands will be re-executed, and the above problem will occur.
