[GitHub] [hadoop] steveloughran opened a new pull request, #5076: HADOOP-18507. VectorIO FileRange type to support a "reference" field
steveloughran opened a new pull request, #5076:
URL: https://github.com/apache/hadoop/pull/5076
Add new reference field; verifies it remains in merging.
also fix up those tests which used string comparison of range values into actual field checking.
### For code changes:
- [ ] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under [ASF 2.0](http://www.apache.org/legal/resolved.html#category-a)?
