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
