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)
0: jdbc:drill:schema=dfs> select * from `big_numeric.json`;
+------------+
|     a1     |
+------------+
| 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. |
