-----------------------------------
Summary: UNION Operator in Hive
Key: HIVE-8385
URL: https://issues.apache.org/jira/browse/HIVE-8385
Project: Hive
Issue Type: Improvement
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.
