IMPALA-10153: Implement SHOW TABLE HISTORY for Iceberg tables
The SHOW TABLE HISTORY works for Iceberg tables and displays the
snapshot history of the table.
An example output:
SHOW TABLE HISTORY iceberg_multi_snapshots;
+----------------------------+---------------------+---------------------+---------------------+
| creation_time | snapshot_id | parent_id |
is_current_ancestor |
+----------------------------+---------------------+---------------------+---------------------+
| 2020-10-13 14:01:07.234000 | 4400379706200951771 | NULL | TRUE
|
| 2020-10-13 14:01:19.307000 | 4221472712544505868 | 4400379706200951771 | TRUE
|
+----------------------------+---------------------+---------------------+---------------------+
Testing:
- iceberg-negative.test was extended to check that SHOW TABLE HISTORY
is not applicable for non-Iceberg tables.
- iceberg-table-history.test: Covers bacis usage of SHOW CREATE
TABLE. Tests on tables created with Impala and also with Spark.
