Reynold Xin created SPARK-7562: ---------------------------------- Summary: Improve error reporting for expression data type mismatch Key: SPARK-7562 URL: https://issues.apache.org/jira/browse/SPARK-7562 Project: Spark Issue Type: Improvement Components: SQL Reporter: Reynold Xin
There is currently no error reporting for expression data types in analysis. It would be great to have that in checkAnalysis. Ideally, it should be the responsibility of each Expression itself to specify the types it requires, and report errors that way. We would need to define a simple interface for that so each Expression can implement. The default implementation can just use the information provided by ExpectsInputTypes.expectedChildTypes. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
