HiveServer2 High Availability in Cloudera Data Warehouse on premises

Cloudera Data Warehouse provides an option to enable active-passive configuration for HiveServer2 (HS2) pods in on premises for Hive and Unified Analytics. By selecting this option, two HS2 pods run simultaneously–one active and the other inactive. When one pod terminates, the inactive pod becomes active--most likey due to a node failure, providing High Availability (HA).

You can enable the Enable Active-Passive Hiveserver HA option while creating a new Hive or Unified Analytics Virtual Warehouse or editing it.

1. Log in to the Cloudera Data Warehouse service.
2. Go to the Virtual Warehouse on which you want to enable HS2 HA, click > Edit, and go to the Sizing and Scaling tab.
3. Select the Enable Active-Passive Hiveserver HA option.
4. Click Apply Changes.
