Component/s: SQL
Affects Version/s: 0.14.0
> UNION Operator in Hive
> ----------------------
>
> Key: HIVE-8385
> URL: https://issues.apache.org/jira/browse/HIVE-8385
> Project: Hive
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 0.14.0
> Reporter: Pardeep Kumar
>
> While Hive has UNION ALL feature, it results in duplicate records and
> customers have to write another complex query or MapReduce job to Dedup the
> duplicate records. UNION feature is must have in Hive as it is in all SQL
> RDBMS as well as in Apache Impala.
> Not sure how much effort will it take given the fact that UNION ALL is
> already available.
