Review request for Ambari, Dmytro Grinenko, Dmitro Lisnichenko, Jonathan
Hurley, Jayush Luniya, and Nate Cole.
Bugs: AMBARI-14581
https://issues.apache.org/jira/browse/AMBARI-14581
Repository: ambari
Description
-------
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.

Waiting for unit test results.
