> 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.
