> Key: HIVE-24969
> URL: https://issues.apache.org/jira/browse/HIVE-24969
> Project: Hive
> Issue Type: Bug

> 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.
