Vitalii Diravka commented on DRILL-1824:
----------------------------------------
[~jnadeau] is right DRILL-1896 is mixed with this Jira. This one is resolved:
{code:java}
apache drill> select * from dfs.home.`/vector/complex/writer/schemaChange`;
+------+---------------+
| a | b |
+------+---------------+
| foo | null |
| bar | null |
| foo2 | {} |
| bar2 | {"x":1,"y":2} |
+------+---------------+
4 rows selected (0.195 seconds) {code}
But DRILL-1896 is not resolved and causes _TestJsonReader#schemaChangeValidate_
to fail.
