------------------------------
Summary: ES adapter doesn't support sort aggregation result
Key: CALCITE-4868
URL: https://issues.apache.org/jira/browse/CALCITE-4868
Project: Calcite
Issue Type: Bug
Components: elasticsearch-adapter
Affects Versions: 1.28.0
Reporter: ZheHu
When I run the following SQL in ES Adapter module(AggregationTest.java):
{code:java}
@Test void testSortAggregation() {
CalciteAssert.that()
.with(newConnectionFactory())
.query("select cat5, max(val1) as MAX_VAL1 from view group by cat5
order by MAX_VAL1 desc, cat5 desc")
.returns("cat5=2; val1=7\n");
}
{code}
I get such exception:
{code:java}
java.lang.IllegalArgumentException: Field MAX_VAL1 not defined for aggs

{code}
AS a result of the ES mapping doesn't contain field "MAX_VAL1", such exception
occurred.
According to the SQL, generated ES scripts should be(I have run it in ES 7.3.2):
{code:java}
{
"aggs": {
"cat5_val1": {
"terms": {
"field": "cat5",
"order": [
{
"_key": "desc"
},
{
"MAX_VAL1": "desc"
}
]
},
"aggs": {
"MAX_VAL1": {
"max": {
"field": "val1"
}
}
}
}
}
}
{code}
