[hive] bad error reporting if a FROM is missing in the nested query in case of
JOIN
-----------------------------------------------------------------------------------
Key: HADOOP-4518
URL: https://issues.apache.org/jira/browse/HADOOP-4518
Project: Hadoop Core
Issue Type: Bug
Reporter: Namit Jain
EXPLAIN FROM
(SELECT DISTINCT C_CXT.USERID FROM C_CXT) A
JOIN
(SELECT FCT_INVITES.* WHERE FCT_INVITES.INVITER_ID <> 0 AND FCT_INVITES.DS =
'2008-10-01') B
ON (A.USERID = B.INVITER_ID) SELECT B.*
The above is missing FROM in the 2nd subquery (B), but the parser returns an
error in JOIN
