HyukjinKwon edited a comment on issue #23325: [SPARK-26376][SQL] Skip inputs without tokens by JSON datasource URL: https://github.com/apache/spark/pull/23325#issuecomment-447618862 Yea, correct. One of the behaviour changes was, After the change, an empty string (no JSON token) produces a row of nulls (`Row(null, null ...)`) in both JSON datasource and JSON functions. Before the change: 1. JSON datasource previously ignored this (no row) instead of `Row(null, null ...)`. 2. JSON functions previously produced `null` instead of `Row(null, null ...)`. However, we're reverting one case of both now.
