Hyukjin Kwon d4d6df2f7d [SPARK-26745][SQL] Revert count optimization in JSON datasource by SPARK-24959 ... ## What changes were proposed in this pull request? This PR reverts JSON count optimization part of #21909. We cannot distinguish the cases below without parsing: ``` [{...}, {...}] ``` ``` [] ``` ``` {...} ``` ```bash # empty string ``` when we `count()`. One line (input: IN) can be, 0 record, 1 record and multiple records and this is dependent on each input. See also https://github.com/apache/spark/pull/23665#discussion_r251276720. ## How was this patch tested? Manually tested. Closes #23667 from HyukjinKwon/revert-SPARK-24959.
