wenfang6 opened a new pull request #26965: Support single quotes json parsing for get_json_object and json_tuple URL: https://github.com/apache/spark/pull/26965 ### What changes were proposed in this pull request? I execute some query as` select get_json_object(ytag, '$.y1') AS y1 from t4`; SparkSQL return null but Hive return correct results. In my production environment, ytag is a json wrapped by single quotes,as follows ``` {'y1': 'shuma', 'y2': 'shuma:shouji'} {'y1': 'jiaoyu', 'y2': 'jiaoyu:gaokao'} {'y1': 'yule', 'y2': 'yule:mingxing'} ``` Then l realized some functions including get_json_object and json_tuple does not support single quotes json parsing. So l provide this PR to resolve the question. ### Why are the changes needed? Enabled for Hive compatibility ### Does this PR introduce any user-facing change? NO ### How was this patch tested?
