Kristopher Kane commented on HIVE-14987:
----------------------------------------
Can see this problem on Hive 1.2.1 Was it fixed in later versions?
> CombineHiveInputFormat with Tez fails to initiate vertex if table is empty

> Key: HIVE-14987
> URL: https://issues.apache.org/jira/browse/HIVE-14987
> Project: Hive
> Issue Type: Bug
> Reporter: Yi Zhang
> Priority: Major
>
> Sometimes user have developed custom inputformat that extends from
> CombineHiveInputFormat due to difficulty of extending from HiveInputFormat
> directly, for example to filter out old data files.
> in this use case, vertex fails to get initialized:
> SELECT city.cid
> FROM
> (select city_id as cid,
> row_number() over(partition by timezone order by population) rnum
> from cities) city
> JOIN
> (select datestr, id from yizhang.emptyparts where datestr >=
> date_sub(current_date(),30)) emp
> on city.cid = emp.id
> ;
