This problem was introduced by <https://issues.apache.org/jira/browse/SPARK-16826> which is designed to improve performance of PARSE_URL().
The same issue exists in the following SQL: ```SQL SELECT PARSE_URL('http://stanzhai.site?p=["abc"]', 'QUERY', 'p') // return null in Spark 2.1+ // return ["abc"] less than Spark 2.1 ``` I think it's a regression. -- Sent from: http://apache-spark-developers-list.1001551.n3.nabble.com/ --------------------------------------------------------------------- To unsubscribe e-mail: dev-unsubscr...@spark.apache.org
