             Summary: Error message not clear when we try to select a field within a map without using an alias
                 Key: DRILL-2972
                 URL: https://issues.apache.org/jira/browse/DRILL-2972
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
            Reporter: Rahul Challapalli
            Assignee: Jinfeng Ni
            Priority: Critical


git.commit.id.abbrev=3b19076

When I try to access a field within a map (without using an alias), below is the error I get.
{code}
0: jdbc:drill:schema=dfs_eea> select map.rm from `data.json`;
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}

There is no message from drill and the chances of users hitting this scenario is very high. So I am marking this as critical.
