Hello, We need to restart the Hive server and metastore components in order to pick up a recent configuration change. (https://gerrit.wikimedia.org/r/c/operations/puppet/+/709484) If possible, I'd like to schedule this operation for 09:00 UTC**this Wednesday: 2021/08/04 The service restart itself should only take a few moments, but YARN processes that are using Hive tables at the time of the restart will likely return an error. Please attempt to schedule any jobs such that they will not coincide with this restart, or be prepared to re-run them in case of failure. If this scheduled maintenance window will cause significant inconvenience for you, then please let me know and I will attempt to re-schedule. The Phabricator task relating to this work is: Kind regards, Ben -- *Ben Tullis*(he/him) Senior Site Reliability Engineer Wikimedia Foundation <https://wikimediafoundation.org/>
