[jira] [Created] (SPARK-38769) [SQL] behavior schema_of_json not same with 2.4.0
gabrywu created SPARK-38769:
-------------------------------
Summary: [SQL] behavior schema_of_json not same with 2.4.0
Key: SPARK-38769
URL: https://issues.apache.org/jira/browse/SPARK-38769
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.1.1
Reporter: gabrywu
When I switch to spark 3.1.1 from spark 2.4.0, I found a built-in function throw errors:
|== Physical Plan == org.apache.spark.sql.AnalysisException: cannot resolve 'schema_of_json(get_json_object(`adtnl_info_txt`, '$.all_model_scores'))' due to data type mismatch: The input json should be a foldable string expression and not null; however, got get_json_object(`adtnl_info_txt`, '$.all_model_scores').; line 3 pos 2; |
But schema_of_json worked well in 2.4.0, So, is it a bug, or a new feature, which doesn't support non-Literal expressions?
