Serge Rielau created SPARK-41931: ------------------------------------ Summary: Improve UNSUPPORTED_DATA_TYPE message for complex types Key: SPARK-41931 URL: https://issues.apache.org/jira/browse/SPARK-41931 Project: Spark Issue Type: Improvement Components: Spark Core Affects Versions: 3.4.0 Reporter: Serge Rielau
spark-sql> SELECT CAST(array(1, 2, 3) AS ARRAY); [UNSUPPORTED_DATATYPE] Unsupported data type "ARRAY"(line 1, pos 30) == SQL == SELECT CAST(array(1, 2, 3) AS ARRAY) ------------------------------^^^ This error message is confusing. We support ARRAY. We just require it to be typed. We should have an error like: [INCOMPLETE_TYPE_DEFINITION.ARRAY] The definition of type `ARRAY` is incomplete. You must provide an element type. For example: `ARRAY\<INT\>`. Similarly for STRUCT and MAP. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
