----------------------------------------

             Summary: Drill has problems with reading json fields when used in a subquery
                 Key: DRILL-2094
                 URL: https://issues.apache.org/jira/browse/DRILL-2094
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
            Reporter: Rahul Challapalli
            Assignee: Jinfeng Ni


git.commit.id.abbrev=3e33880

Data Set :
{code}
{
  "id" : 1,
  "list" : [1,2]
}
{code} 

The below query works
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select id from `temp1.json` order by list[0];
+------------+
|     id     |
+------------+
| 1          |
+------------+
1 row selected (0.146 seconds)
{code}

However when I used the same exact query as part of a sub-query, I get an error from drill

{code}
0: jdbc:drill:schema=dfs.drillTestDir> select s.id from (select id from `temp1.json` order
by list[0]) s;
Query failed: SqlValidatorException: Table 'list' not found

Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}

Explain plan also does not work and it returns the same problem
