We do not support join condition on complex type. But the error message is not clear to end user.
{code}
0: jdbc:drill:schema=dfs.drillTestDirComplexJ> select a.id from `complex.json` a left outer join `complex.json` b on a.oooa=b.oooa;
Query failed: RemoteRpcException: Failure while running fragment., Failure while trying to materialize incoming schema. Errors:
Error in expression at index 0. Error: Missing function implementation: [hash(MAP-REQUIRED)]. Full expression: null.. [ 6a61d61f-670f-4ddc-bb1d-09a47f49f38e on qa-node120.qa.lab:31010 ]
[ 6a61d61f-670f-4ddc-bb1d-09a47f49f38e on qa-node120.qa.lab:31010 ]
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}
Here oooa is a complex type:
{code}
{
"oooa": {
"oa": {
"oab": {
"oabc": [
{
"rowId": 1
},
{
"rowValue1": 1,
"rowValue2": 1
}
]
}
}
}
}
{code}
