Zhihua Deng created HIVE-24969: ---------------------------------- Summary: Predicates are removed by PPD when left semi join followed by lateral view Key: HIVE-24969 URL: https://issues.apache.org/jira/browse/HIVE-24969 Project: Hive Issue Type: Bug Components: Logical Optimizer Reporter: Zhihua Deng Assignee: Zhihua Deng
Step to reproduce: {code:java} select count(distinct logItem.triggerId) from service_stat_log LATERAL VIEW explode(logItems) LogItemTable AS logItem where logItem.dsp in ('delivery', 'ocpa') and logItem.iswin = true and logItem.adid in ( select distinct adId from ad_info where subAccountId in (16010, 14863)); {code} For predicates _logItem.dsp in ('delivery', 'ocpa')_ and _logItem.iswin = true_ are removed when doing ppd: JOIN -> RS -> LVJ. The JOIN has candicates: logitem -> [logItem.dsp in ('delivery', 'ocpa'), logItem.iswin = true],when pushing them to the RS followed by LVJ, none of them are pushed, the candicates of logitem are removed finally by default, which cause to the wrong result. -- This message was sent by Atlassian Jira (v8.3.4#803005)
