When I set this parameter on a SYSTEM level, it seems to work correctly:
{code}
0: jdbc:drill:schema=dfs> alter system set `store.json.all_text_mode`= true;
+------------+------------+
| ok | summary |
+------------+------------+
| true | store.json.all_text_mode updated. |
+------------+------------+
1 row selected (0.079 seconds)

+------------+

+------------+
| 14994882832830675451 |
+------------+
1 row selected (0.07 seconds)
{code}
Other "ALTER SESSION" parameters that I tried and they seem to work:
* alter session set `exec.errors.verbose`= true;
* alter session set `planner.enable_hashjoin`=false;
* alter session set `planner.enable_hashagg`=false;
Not the same as DRILL-1769 (see below)
{code}
0: jdbc:drill:schema=dfs> alter session set `planner.enable_hashagg`= false;
+------------+------------+
| ok | summary |
+------------+------------+
| true | planner.enable_hashagg updated. |
