Hi all, As discussed in SPIP: Standardize Exception Messages in Spark ( https://docs.google.com/document/d/1XGj1o3xAFh8BA7RCn3DtwIPC6--hIFOaNUNSlpaOIZs/edit?usp=sharing), improving error message quality in Apache Spark involves establishing an error message guideline for developers. Error message style guidelines are common practice across open-source projects, for example PostgreSQL ( https://www.postgresql.org/docs/current/error-style-guide.html).
To move towards the goal of improving error message quality, we would like to start building an error message guideline. We have attached a rough draft to kick off this discussion: https://docs.google.com/document/d/12k4zmaKmmdm6Pk63HS0N1zN1QT-6TihkWaa5CkLmsn8/edit?usp=sharing . Please let us know what you think should be in the guideline! We look forward to building this as a community. Thank you, Karen Feng
