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), we write the following PDBs:

Master

We only allow a single Master to be offline at any given time, regardless of the number of replicas or roleGroups.

RegionServer

We only allow a single RegionServer 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

We only allow a single RestServer to be offline at any given time, regardless of the number of replicas or roleGroups.
