OmniHBaseGSI
Before upgrading the OmniHBaseGSI feature, stop the HBase cluster, replace the software packages of the current version with those of the new version, and then restart the HBase cluster. If the OmniHBaseGSI feature is no longer used, you can stop the HBase cluster, delete the software packages and those configuration items added during the installation, and restart the HBase cluster to complete the uninstallation.
Upgrading the Software
- Stop the HBase cluster.
