The following query fails to group properly.
{code:java}
SELECT date, COUNT(1)
FROM (
    SELECT DISTINCT
        id,
        date,
        status
    FROM table(dfs.`path`(type => 'text', fieldDelimiter => ',', extractHeader => TRUE))
)
GROUP BY 1{code}
This also fails to group properly.
{code:java}
SELECT date, COUNT(1)
FROM (
    SELECT
        id,
        date,
        status
    FROM table(dfs.`path1`(type => 'text', fieldDelimiter => ',', extractHeader => TRUE))
    UNION
    SELECT
        id,
        date,
        status
    FROM table(dfs.`path2`(type => 'text', fieldDelimiter => ',', extractHeader => TRUE))
)
GROUP BY 1
{code}
