> In https://github.com/apache/spark/pull/26418, a setting spark.sql.dialect.intervalOutputStyle
was implemented, to control interval output style. This PR also removed "toString" from CalendarInterval.
This change got reverted in https://github.com/apache/spark/pull/27304, and the CalendarInterval.toString
got implemented back in https://github.com/apache/spark/pull/26572.
> But it behaves differently now: In 2.4 "4 weeks 2 days" are returned, and 3.0 returns
"30 days".
> Thriftserver uses HiveResults.toHiveString, which uses CalendarInterval.toString to return
interval results as string.  The results are now different in 3.0
