> BTW, I think PR description should not say it's for consistency with spark-sql shell. `df.show` displays top-level null value as `NULL`, but inner field null value as `null`. This is the major motivation of the fix. Actually, previously, the top-level is consistent with the inner null display with `null`. This PR mainly thinks that the mainstream database uses `NULL` instead of `null` when displaying null, and `NULL` is a better nice string representation. If it's affecting something else, I think we should look at it again, sorry ~ : ) > For example, we don't display a table the same way in those REPLs. BTW, For apache spark, spark-sql and spark-shell are two different REPLs, but they are only user interaction interfaces. Shouldn't the displayed content be the same? At least in terms of the result set. -- This is an automated message from the Apache Git Service.
