Maintenance in Yandex Managed Service for Apache Spark™

Maintenance includes:

• Automatic installation of Apache Spark™ updates and patches for hosts (including for stopped clusters).
• Other maintenance activities.

Maintenance windowMaintenance window

You can set the maintenance window when creating a cluster or updating its settings:

• The At any time option (default) allows performing maintenance at any time.
• The By schedule option allows you to select the day of the week and UTC time interval for the maintenance. For example, you can choose a time when the cluster is least loaded.

Both active and stopped clusters are subject to maintenance. Maintenance operations may include DBMS updates, applying patches, etc.

In the management console, you select the maintenance start time as an hour interval. In other interfaces, you specify this interval by its sequence number, from 1 to 24.

For example, to start maintenance in the interval from 00:00 to 01:00, put 1; from 04:00 to 05:00, 5.
