Cheng Lian created SPARK-12323: ---------------------------------- Summary: Don't assign default value for non-nullable columns of a Dataset Key: SPARK-12323 URL: https://issues.apache.org/jira/browse/SPARK-12323 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 1.6.0, 2.0.0 Reporter: Cheng Lian Assignee: Cheng Lian
For a field of a Dataset, if it's specified as non-nullable in the schema of the Dataset, we shouldn't assign default value for it if input data contain null. Instead, a runtime exception with nice error message should be thrown, and ask the user to use {{Option}} or nullable types (e.g., {{java.lang.Integer}} instead of {{scala.Int}}). -- 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
