Pull request overview
This PR addresses issue HDDS-14417 by skipping the creation of pseudo files for allocated but unused blocks when committing empty files. The change prevents unnecessary entries in the deleted table for files with zero data size.
Changes:
- Modified the
wrapUncommittedBlocksAsPseudoKey()method to return null when the file's data size is 0, even if there are uncommitted blocks - Added test coverage for empty file scenarios in both regular key commit and S3 multipart upload commit operations
