> The HA Group Store is composed of ZK nodes from two ZK clusters, one from
> each HBase cluster. As described in the [design
> document|https://docs.google.com/document/d/1Qw1MM7jten_h2oGMWZRC_8Py4K-01S9VyPMXdjE3Gj0/edit?pli=1&tab=t.0#heading=h.5s1sz96x6dg9]
> for PHOENIX-7562,
> * HAGroupStoreClient runs on the server side inside the HBase region
> servers, listens to the HA Group Store for updates on the HA group records,
> and also updates the HA group records.
> * HAGroupStoreManager coordinates server-side behavior with HA Group Store
> and uses HAGroupStoreClient to get updates from and make updates on HA Group
> Store. It also provides an RPC endpoint for DualClusterClient to retrieve HA
> group records.
> This subtask is to enhance HAGroupStoreManager and HAGroupStore introduced in
> PHOENIX-7493 for consistent failover.
