Maxim Gekk created SPARK-26740: ---------------------------------- Summary: Statistics for date and timestamp columns depend on system time zone Key: SPARK-26740 URL: https://issues.apache.org/jira/browse/SPARK-26740 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.4.0 Reporter: Maxim Gekk
While saving statistics for timestamp/date columns, default time zone is used in conversion of internal type (microseconds or days since epoch) to textual representation. The textual representation doesn't contain time zone. So, when it is converted back to internal types (Long for TimestampType or DateType), the Timestamp.valueOf and Date.valueOf are used in conversions. The methods use current system time zone. If system time zone is different while saving and retrieving statistics for timestamp/date columns, restored microseconds/days since epoch will be different. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
