guixiaowen opened a new pull request, #46243:
URL: https://github.com/apache/spark/pull/46243
### What changes were proposed in this pull request?
I am doing Hive SQL to switch to Spark SQL.
In Hive SQL
hive> explain select *,row_number() over (partition by day) rn from
testdb.zeropart_db;
OK
Explain
In Spark SQL
spark-sql> explain select *,row_number() over (partition by age ) rn from
testdb.zeropart_db;
plan
== Physical Plan ==
org.apache.spark.sql.AnalysisException: Window function row_number()
requires window to be ordered, please add ORDER BY clause. For example SELECT
row_number()(value_expr) OVER (PARTITION BY window_partition ORDER BY
window_ordering) from table
Time taken: 0.172 seconds, Fetched 1 row(s)
For better compatibility with migration. For better compatibility with
migration, new parameters are added to ensure compatibility with the same
behavior as Hive SQL
### Why are the changes needed?
