[jira] [Created] (DRILL-1278) Selecting individual fields from a
map with a join fails with IllegalStateException
Mehant Baid created DRILL-1278:
----------------------------------
Summary: Selecting individual fields from a map with a join fails with IllegalStateException
Key: DRILL-1278
URL: https://issues.apache.org/jira/browse/DRILL-1278
Project: Apache Drill
Issue Type: Bug
Reporter: Mehant Baid
Assignee: Mehant Baid
I have the following json file
bug.json
{"col" : {"name" : "foo", "id": 1}, "col1": 1}
{"col" : {"name" : "bar", "id": 2}, "col1": 2}
Have the same data in another file bug1.json.
The following query succeeds and returns the right result.
select b.col from dfs.`bug.json` b, dfs.`bug1.json` b1 where b.col1 = b1.col1;
However selecting an individual field from the 'col' map fails.
select b.col.name from dfs.`bug.json` b, dfs.`bug1.json` b1 where b.col1 = b1.col1;
Below is the stack trace
java.lang.IllegalStateException
Incoming batch has an empty schema. This is not allowed.
