Update the minor version of an ApsaraDB for HBase cluster in the ApsaraDB for HBase console - ApsaraDB for HBase

This topic describes how to update the minor version of an ApsaraDB for HBase cluster in the ApsaraDB for HBase console. This topic also describes the feature updates in each minor version.

Important

The update does not interrupt the ApsaraDB for HBase service. The system performs a rolling update on the ApsaraDB for HBase cluster. Before the RegionServer restarts, all regions are moved to other servers to minimize the impact on your workloads. Jitters may occur during the update, but the ApsaraDB for HBase cluster remains available. You can perform minor version updates based on your business requirements.
The amount of time that is required to update the minor version of an ApsaraDB for HBase cluster varies based on the size of the ApsaraDB for HBase cluster and the number of regions in the ApsaraDB for HBase cluster. A larger cluster requires more time to update the minor version. In most cases, ApsaraDB for HBase takes less than 10 minutes to update a cluster that contains two core nodes and 100 regions. ApsaraDB for HBase may take more than 1 hour to update a cluster that contains a large number of core nodes and more than 1,000 regions.

Procedure

Log on to the ApsaraDB for HBase console.
In the top navigation bar, select the region where the cluster that you want to manage is deployed.
On the Clusters page, find the cluster and click the ID of the cluster.
In the left-side navigation pane, click Database Connection.
In the upper-right corner, click Upgrade Minor Version.
