Ferdinand Xu commented on HIVE-7553:
------------------------------------
[~leftylev] release notes are as below:
The newly added parameter "hive.reloadable.aux.jars.path" is serving for the
complement of the previous configuration "hive.aux.jars.path". In order to
making the HiveServer2 as a service, it should not be restarted when the
auxiliary jars changed. In this JIRA, a new command "reload" with a parameter
"hive.reloadable.aux.jars.path" can be used for avoid the scheduling
maintenance window for every jar change. User can execute the reload command
via the beeline to make the HS2 aware of the changes made in the path specified
by the parameter "hive.reloadable.aux.jars.path". And the supported changes
including adding, removing or updating jar files.

> When user needs to refresh existing or add a new jar to HS2, it needs to
> restart it. As HS2 is service exposed to clients, this requires scheduling
> maintenance window for every jar change. It would be great if we could avoid
> that.
