@InterfaceAudience.Private public class HBaseInterClusterReplicationEndpoint extends HBaseReplicationEndpoint
ReplicationEndpoint
implementation for replicating to another HBase cluster.
For the slave cluster it selects a random number of peers
using a replication ratio. For example, if replication ration = 0.1
and slave cluster has 100 region servers, 10 will be selected.
A stream is considered down when we cannot contact a region server on the peer cluster for more than 55 seconds by default.
