----------------------------------

             Summary: limit partition number involved in a table scan
                 Key: HIVE-6492
                 URL: https://issues.apache.org/jira/browse/HIVE-6492
             Project: Hive
          Issue Type: New Feature
          Components: Query Processor
    Affects Versions: 0.12.0
            Reporter: Selina Zhang
             Fix For: 0.13.0


To protect the cluster, a new configure variable "hive.limit.query.max.table.partition" is
added to hive configuration to
limit the table partitions involved in a table scan. 

The default value will be set to -1 which means there is no limit by default. 

This variable will not affect "metadata only" query.
