devmadhuu opened a new pull request, #10199:
URL: https://github.com/apache/ozone/pull/10199
## What changes were proposed in this pull request?
This PR handles failed container import cleanup on the DataNode.
`KeyValueContainer.cleanupFailedImport()` now deletes the chunks/ directory
before deleting the metadata/ directory. If cleanup is interrupted or partially
fails between child-
directory deletions, the remaining on-disk state now preferentially
preserves metadata instead of leaving a harder-to-diagnose chunks/-only
residual directory.
A focused test was added to inject an import cleanup failure at metadata
deletion and verify that chunks/ has already been removed while metadata/
remains.
