             Summary: Allow hive.metastore.limit.partition.request to be user configurable
                 Key: HIVE-18559
                 URL: https://issues.apache.org/jira/browse/HIVE-18559
             Project: Hive
          Issue Type: Bug
          Components: Metastore
            Reporter: Mohit Sabharwal
            Assignee: Mohit Sabharwal


HIVE-13884 introduced hive.metastore.limit.partition.request to limit the number of partitions that can be requested from the Metastore for a given table.

This config is set by cluster admins to prevent ad-hoc queries from putting memory pressure on HMS. But the limit can be too restrictive for some (savvy) users who require the ability to set a higher limit for a subset of workloads (during low HMS memory pressure, for example). Such users generally instruct admins not to set this confg.
