> 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.
