----------------------------------------
Summary: Drill interpreting a scalar as a map or array in an order by stmt when used with flatten
Key: DRILL-2119

Project: Apache Drill
Issue Type: Bug
Components: Execution - Operators
Reporter: Rahul Challapalli
Assignee: Jason Altekruse
git.commit.id.abbrev=3e33880
Data Set :
{code}
{
"uid": 1,
"map": {
"rm": [
{
"mapid": "m1",
"mapvalue": {
"col1": 1,
"col2": [0,1,2,3,4,5]
},
"rptd": [
{ "a": "foo"},
{ "b": "boo"}
]
},
{
"mapid": "m2",
"mapvalue": {
"col1": 0,
"col2": []
},
"rptd": [
{ "a": "bar"},
{ "c": 1},
{ "d": 4.5}
]
}
]
},
"lst_lst" : [[1,2,3,4,5],[2,3,4,5,6]]
}
{code}
Query :
{code}
select flatten(rptd) from (select uid, d.map.rm[0].rptd rptd, flatten(d.lst_lst[1]) lst1 from `temp4.json` d) s1 order by s1.lst1;
{code}
When we remove the flatten from the top level query, things work fine
{code}
select s1.lst1 from (select uid, d.map.rm[0].rptd rptd, flatten(d.lst_lst[1]) lst1 from `temp4.json` d) s1 order by s1.lst1
+------------+
| lst1 |
+------------+
| 2 |
| 3 |
| 4 |
| 5 |
| 6 |
+------------+
{code}
Log File contents for the error

java.lang.RuntimeException: java.lang.UnsupportedOperationException: Map, Array or repeated scalar type should not be used in group by, order by or in a comparison operator. Drill does not support compare between MAP:REQUIRED and MAP:REQUIRED.
