Hi Bennie, thanks for using Hive. Could you please post more information so that we can better help you? If possible, please post the version of Hive that you use and the result of “explain” command, i.e., when you run “explain CREATE TABLE ipv4table AS
SELECT logon.IP, ipv4.Country
FROM
(SELECT * FROM logontable WHERE isIpv4(IP)) logon
LEFT OUTER JOIN
(SELECT StartIp, EndIp, Country FROM ipv4geotable) ipv4 ON isIpv4(logon.IP)
WHERE ipv4.StartIp <= logon.IP AND logon.IP <= ipv4.EndIp;”
