Description

I have a relatively complicated hive query using CombinedHiveInputFormat:
set hive.exec.dynamic.partition.mode=nonstrict;
set hive.exec.dynamic.partition=true;
set hive.exec.max.dynamic.partitions=1000;
set hive.exec.max.dynamic.partitions.pernode=300;
set hive.input.format=org.apache.hadoop.hive.ql.io.CombineHiveInputFormat;
INSERT OVERWRITE TABLE keyword_serp_results_no_dups PARTITION(week) select distinct keywords.keyword, keywords.domain, keywords.url, keywords.rank, keywords.universal_rank, keywords.serp_type, keywords.date_indexed, keywords.search_engine_type, keywords.week from keyword_serp_results keywords JOIN (select domain, keyword, search_engine_type, week, max_date_indexed, min(rank) as best_rank from (select keywords1.domain, keywords1.keyword, keywords1.search_engine_type, keywords1.week, keywords1.rank, dupkeywords1.max_date_indexed from keyword_serp_results keywords1 JOIN (select domain, keyword, search_engine_type, week, max(date_indexed) as max_date_indexed from keyword_serp_results group by domain,keyword,search_engine_type,week) dupkeywords1 on keywords1.keyword = dupkeywords1.keyword AND keywords1.domain = dupkeywords1.domain AND keywords1.search_engine_type = dupkeywords1.search_engine_type AND keywords1.week = dupkeywords1.week AND keywords1.date_indexed = dupkeywords1.max_date_indexed) dupkeywords2 group by domain,keyword,search_engine_type,week,max_date_indexed ) dupkeywords3 on keywords.keyword = dupkeywords3.keyword AND keywords.domain = dupkeywords3.domain AND keywords.search_engine_type = dupkeywords3.search_engine_type AND keywords.week = dupkeywords3.week AND keywords.date_indexed = dupkeywords3.max_date_indexed AND keywords.rank = dupkeywords3.best_rank;

This query use to work fine until I updated to r991183 on trunk and started getting this error:

This query works if I don't change the hive.input.format.
set hive.input.format=org.apache.hadoop.hive.ql.io.CombineHiveInputFormat;

I've narrowed down this issue to the commit for HIVE-1510. If I take out the changeset from r987746, everything works as before.
