<!-- Explain the changes in the pull request below: -->
<!-- We recommend you review the checklist/tips before submitting a pull
request. -->
- [ ] Did you create an [Apache
Jira](https://issues.apache.org/jira/projects/THRIFT/issues/) ticket?
([Request account here](https://selfserve.apache.org/jira-account.html), not
required for trivial changes)
- [ ] If a ticket exists: Does your pull request title follow the pattern
"THRIFT-NNNN: describe my issue"?
- [ ] Did you squash your changes to a single commit? (not required, but
preferred)
- [ ] Did you do your best to avoid breaking changes? If one was needed,
did you label the Jira ticket with "Breaking-Change"?
- [ ] If your change does not involve any code, include `[skip ci]` anywhere
in the commit message to free up build resources.
