I tried dev@drill.apache.org<mailto:dev@drill.apache.org>, but got no response, so I
am hoping that user@drill.apache.org<mailto:user@drill.apache.org> will be able to help
out.
--------------------------------------------------------
Can someone help or point me to where I can maybe get some help?
I am trying to figure out why I am getting a ClassCastException when I do the following query.
If I change the "FROM" clause to just "FROM (VALUES(0))" it works just fine, but whenever
I have "FROM" to an HBase table, I get the error. I know that the HBase table is valid because
if I remove the WHERE clause, the query does not throw an error.
SELECT b.`date` FROM (
SELECT TO_DATE(CONCAT(a.`jArray`[0], '-', a.`jArray`[1], '-', a.`jArray`[2]), 'yyyy-MM-dd')
`date` FROM (
SELECT CONVERT_FROM(REGEXP_REPLACE('["2016":"08":"03"]', ':', ','), 'JSON') `jArray`
--FROM (VALUES(0))
FROM `hbase`.`SomeValidTable`
) a
) b
WHERE b.`date` = '2016-08-03'
LIMIT 1
