Apache Spark reassigned SPARK-7562: ----------------------------------- Assignee: Apache Spark > 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 > Assignee: Apache Spark > > There is currently no error reporting for expression data types in analysis > (we rely on "resolved" for that, which doesn't provide great error messages > for types). 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. > cc [~marmbrus] what we discussed offline today. -- 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
