Allowed Pod disruptions

You can configure the permitted Pod disruptions for HBase nodes as described in Allowed Pod disruptions.

Unless you configure something else or disable our PodDisruptionBudgets (PDBs), the default PDBs are configured as follows:

Master

Only a single Master is allowed to be offline at any given time, regardless of the number of replicas or roleGroups.

RegionServer

Only a single RegionServer is allowed to be offline at any given time, regardless of the number of replicas or roleGroups, to have as little data unavailable as possible at any given time.

RestServer

Only a single RestServer is allowed to be offline at any given time, regardless of the number of replicas or roleGroups.
