> During an Express Upgrade, all of the tasks for Hive Server and Hive MetaStore run in
parallel, so if these components have multiple hosts, then running in parallel can cause errors
during the upgrade.
> E.g., Hive Server copies tarballs, which can only run one at a time. Hive MetaStore updates
the schema, and only one can run at a time.
