> [~lpinter] have noticed that this patch has some sideffect:
> in HIVE-23164 the patch have added a {{ThreadPool#shutdown}} to
> {{HMSHandler#shutdown}} - which could cause trouble in case a {{HMSHandler}}
> is shutdown and a new one is created
> I was looking for cases in which a HMSHandler is created inside the metastore
> (beyond the one HiveMetaStore is using) - and I think tasks like
> PartitionManagementTask which uses Msck which uses HMC to access the
> metastore - and they close the client - which closes the hmshandler client ;
> which will shut down the threadpool
