Niranjan Jayakar created SPARK-44816: ----------------------------------------
Summary: Cryptic error message when UDF associated class is not found Key: SPARK-44816 URL: https://issues.apache.org/jira/browse/SPARK-44816 Project: Spark Issue Type: Improvement Components: Connect Affects Versions: 3.5.0 Reporter: Niranjan Jayakar When a Dataset API is used that either requires or is modeled as a UDF, the class defining the UDF/function should be uploaded to the service fist using the `addArtifact()` API. When this is not done, an error is thrown. However, this error message is cryptic and is not clear about the problem. Improve this error message to make it clear that an expected class was not found. -- 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
