MaxGekk opened a new pull request #28687: URL: https://github.com/apache/spark/pull/28687
### What changes were proposed in this pull request? 1. Replace `def dateFormatter` to `val dateFormatter`. 2. Modify the `date formatting in hive result` test in `HiveResultSuite` to check modified code on various time zones. ### Why are the changes needed? To avoid creation of `DateFormatter` per every incoming date in `HiveResult.toHiveString`. This should eliminate unnecessary creation of `SimpleDateFormat` instances and compilation of the default pattern `yyyy-MM-dd`. The changes can speed up processing of legacy date values of the `java.sql.Date` type which is collected by default. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Modified a test in `HiveResultSuite`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
