>
> Key: IMPALA-10725
> URL: https://issues.apache.org/jira/browse/IMPALA-10725
> Project: IMPALA
> Issue Type: New Feature
> Reporter: Quanlong Huang
> Assignee: Shikha Asrani
> Priority: Critical
>
> Since HIVE-19899, Hive supports JSON format tables officially. It'd be good to add the same functionality for Impala.
> Subtasks can be:
> * Support loading metadata of JSON format tables. Make statements that don't need to read data files work first, e.g. DESCRIBE, SHOW CRETATE TABLE, SHOW PARTITIONS, etc.
> * Support creating JSON format tables by "{{STORED AS JSONFILE"}} clause.
> * Support reading JSON format tables. All SELECT queires should work.
> * Support writing to JSON format tables.
