From document I know that,now coral support:
Hive to Trino
Hive to Spark
Trino to Spark
Spark to other is not support, but many company mainly use sparksql, it may be very useful to to support sparksql to others
from coral.
Spark SQL is compatible with Hive QL so using the coral-hive
module for Spark queries can be a good start. Is there a specific difference between Spark SQL and Hive QL that you want to see supported?

case 1:
SELECT
event.event_info [ 'key1' ]
FROM
test.test1
limit 1
with event an complex type: event struct<event_info map<string, string>>
get error:
org.apache.calcite.runtime.CalciteContextException: At line 0, column 0: Table 'event' not found
case 2:
SELECT
uid,
percentile_approx(score, ARRAY(0.5, 0.9, 0.99)) AS pa
FROM
tmp.test2
GROUP BY
uid
ORDER BY
uid ASC
get error:
CalciteContextException: At line 0, column 0: Expression 'score' is not being grouped
case 3:
create table if not exists test.test4 as
select * from test.test3
get error:
Unhandled Hive AST token 665 TOK_CREATETABLE
case 4:
select location,count(1) from tmp.room
where location = 1
group by 1
get error:
At line 0, column 0: Expression 'location' is not being grouped
There also have some other error
from coral.
Spark SQL is compatible with Hive QL
I don't think it's fully compatible. For instance, Spark's raw string literal r'...'
and ILIKE
ar unsupported in Hive.
