> I have a relatively complicated hive query using CombinedHiveInputFormat:

> 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,

> 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 =
