>
> Key: SPARK-32611
> URL: https://issues.apache.org/jira/browse/SPARK-32611
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.0.0, 3.0.1
> Reporter: Sumeet
> Priority: Major
>
> *How to reproduce this behavior?*
> * TZ="America/Los_Angeles" ./bin/spark-shell
> * sql("set spark.sql.hive.convertMetastoreOrc=true")
> * sql("set spark.sql.orc.impl=hive")
> * sql("create table t_spark(col timestamp) stored as orc;")
> * sql("insert into t_spark values (cast('2100-01-01 01:33:33.123America/Los_Angeles' as timestamp));")
> * sql("select col, date_format(col, 'DD') from t_spark where col = cast('2100-01-01 01:33:33.123America/Los_Angeles' as timestamp);").show(false)
> *This will return empty results, which is incorrect.*
> * sql("set spark.sql.orc.impl=native")
> * sql("select col, date_format(col, 'DD') from t_spark where col = cast('2100-01-01 01:33:33.123America/Los_Angeles' as timestamp);").show(false)
> *This will return 1 row, which is the expected output.*
>
> The above query using (True, hive) returns *correct results if pushdown filters are turned off*.
> * sql("set spark.sql.orc.filterPushdown=false")
> * sql("select col, date_format(col, 'DD') from t_spark where col = cast('2100-01-01 01:33:33.123America/Los_Angeles' as timestamp);").show(false)
> *This will return 1 row, which is the expected output.*
