xichen01 opened a new pull request, #4821: URL: https://github.com/apache/ozone/pull/4821
## What changes were proposed in this pull request? When deleting a file, DN will check whether the Block file to be deleted exists or not in the `FilePerBlockStrategy#deleteChunk`. This step of checking for the existence of a Block file can be omitted, and basically does not change the behavior of `FilePerBlockStrategy#deleteChunk`. This can reduce the IO-times of `FilePerBlockStrategy#deleteChunk` the `FilePerBlockStrategy#deleteChunk` ### `FilePerBlockStrategy#deleteChunk` Change - For an existing file `FilePerBlockStrategy#deleteChunk` is no change in the result, just one less once IO with System. - For non-existent files, the `FilePerBlockStrategy#deleteChunk' function behaves the same as before the change, the only difference is that it prints a log of successful deletions. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-8748 ## How was this patch tested? existing test -- This is an automated message from the Apache Git Service.
