Key: ASTERIXDB-2483
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2483
Project: Apache AsterixDB
Issue Type: Bug
Components: COMP - Compiler, RT - Runtime, SQL - Translator SQL++
Affects Versions: 0.9.5
Environment: Linux
Reporter: Michael J. Carey

This is the schema:
{noformat}
CREATE TYPE Test AS open { unique2: int64 };
CREATE DATASET wisconsin_5gb(Test) PRIMARY KEY unique2;
{noformat}
This is the query:
{noformat}
SELECT
min(t.oddOnePercent) as min,
max(t.oddOnePercent) as max,
count(distinct t.oddOnePercent) as cnt
FROM wisconsin_5gb t;
{noformat}
The plan for this query:
{noformat}
distribute result [$$46]
-- DISTRIBUTE_RESULT |UNPARTITIONED|
exchange
-- ONE_TO_ONE_EXCHANGE |UNPARTITIONED|
project ([$$46])
-- STREAM_PROJECT |UNPARTITIONED|
assign [$$46] <- [{"min": $$48, "max": $$49, "cnt": $$50}]
