Quanlong Huang updated IMPALA-10725:
------------------------------------
Description:
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.
